Title: EVERYTHING Trailer Brake Controllers
Post by: mcauto on 06/29/03 12:00 PM
My brake controller comes with a option to hook up a wire to the back-up lights. This will disable the trailer brakes when backing up. Can anybody tell me an easy spot to hook this wire up to?   THANKS

If you don't mind my asking.....what kind of controller do you have? I have been at this for a while (non-professional) and I have never heard of that option.

Electric trailer brakes don't work in reverse very well anyways. All you get is some drag from the brake pucks but no brake shoe contact. Maybe I can learn something new here!  :)

Paging SS, We need your CD on wiring.

Hmmm... This is unusual, I've never heard of this before on the controller end, but then again, that's not saying much.

My understanding is that it's more common to have the reverse lights signal go directly to the trailer, and the brakes are disabled there, locally on the trailer. This is especially used with surge brakes, where the act of backing up would tend to set the brakes.

But to feed it to the controller, you need a signal from inside the cab. mcatuo: you don't say what year truck you have. I only have information on '02 wiring, so if you have an '03 it's very likely that this information is wrong. Furthermore, I have not tested this to see if it works, this information is only from reading the service manual.

Down by the driver's left foot is a relay/connector block, covered by a black plastic panel. The panel is held in place by a large hex shaped plastic thumbscrew. This is where the socket for the trailer brake controller resides. That socket (along with the plug/harness from GM) should give you everything you need, except the reverse lights signal. Also in this block, at the lower left position, is a large connector with several wires. One of these is a small light green wire, which should be the reverse lights signal you are seeking.

I would test it out with a volt meter or a small test lamp before cutting/splicing that wire.

 I got the controller about 3 years ago. It worked great in my old dead Ford. The name on the control is POWERSTOP model #500-PS.
 I am pulling a 25' long car trailer and it does not have back-up lights on it. Although I am thinking about installing some on it to help backing up at night.
 I do own a '02 So hopefully this information will help me.
 Thanks for the help SS I should be wiring this weekend.

I did a search and couldn't find the answer...

I need to rent a Bobcat loader.  Bobcat of St. Louis will give me a trailer for transport free with the rental, but it has electric brakes.  

What do I need in my Av to control these brakes?  It's going to cost me $160 round trip to have the Bobcat delivered--I'd rather pick it up if I can.

Any ideas?

BTW, the two Bobcat's that I'm looking at are 2700lbs and 3700lbs...I may go with the bigger one of these.

Well, if your Av has the trailering package, there is a jack on the back of your truck. If the trailer has electric brakes (or any lighting at all, for that matter) it will have a cable with some sort of plug on it. My guess it will either be the 7-pin 'spade' plug or 6-pin. If it's the 7-pin you should just be able to plug it in. If it's the 6-pin you'll need an adapter.

As for brake controllers, I think your best bet is the Prodigy. They can be found for $100-130 and can usually be ordered with the harness you need (plug on one end for the controller and on the other for your specific truck - the year is important as 2003 and 2002 are different). You'll have to order it unless you have a local RV dealer that carries it.

My 2003 came with the fuse installed - not sure if the 2002's did or not.

Hope that helps...

Another route to go is to tow it without the trailer breaks. I've towed this with my Z-71 with no problems. Go slow[er] and easy. Sure it takes longer to stop but nothing unreasonable. I went about 75mi with it. A double Axel trailer with just correct hit of tung weight, she will do fine. If she sways side to side move the bobcat fwd.

example [not a real example]

sway at 40 move weight fwd 1 foot
sway at 55 move weight  fwd 6 inches
sway at 75 kiss, ass good by  :4:

If you plan to tow allot, by all means get equipped.

Alaska Av,  thanks for the info.

What was the lifting capacity of that bobcat?  I was give a rental price on two different models that my truck could tow.  One could lift 500lbs , the other 750lbs.  He originally quoted me on the 1950lbs capacity 'cat, but said I'd need a 3/4 ton truck for it.

I don't think they'll let me use their trailer without the brake controller.

I may be taking another route anyway....I have someone coming out on Sunday to look at my yard and give me a quote to do the work for me.   I figure I'd be spending $300+ for bobcat rental with delivery, $230 for dumpster rental, plus all my own labor.  If he comes in around $800 for the job, he's hired, and my back will be thankful.  If it is much more than that, back to the drawing board....

Under the dash just above and to the right of the parking break is a 'black box' with a nut on the front. Unscrew it and plug the connector in. I don't recall exactly where, but there was only one way it would fit and the connector that came with the prodigy (ordered with it specific to 2003 Av) had a diagram. There may even be one in the manual.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: Alaska_AV. on 06/05/03 03:22 PM
I'm not sure the lifting capacity, but I think it was rated at 95 horse power. The rental joint rented me the trailer also. With all the equipment I rent, I just about have the yard guy convinced his next truck will be an AV ;D
My old F-150 had half the towing capacity this AV has. about 3500lb.  that sucked

Great brake controller for a great price, this was posted on PopUpTimes and few people have ordered them and said the company is a good company to deal with shipping was about $8.00 or less, one guy got it for $5.40.  So of course I had to share the deal with the Av owners too!

http://www.rvwholesalers.com/

If you are considering upgrading to one now is the time.  I know I love towing with my Prodigy wouldn't use any other controller now.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: Traz on 05/21/03 12:08 AM
 I got about the same price recently from Rjays.  It was $106, but included shipping.  Actually a little cheaper for most if you add shipping to the other one.  Plus if you buy a harness the shipping is free on that also.  Was very pleased with service from Rjays too.

A while back, I hooked up my brake controller and all was well.  I adjusted the brake sensitivity, and was off towwing without a problem.  I have been towwing for 4 weeks now without a glitch.  Well, now when I hit my brakes while towwing, I get nothing.  The display reads that the trailer is not connected.  I have all my lights, brake lights, blinkers......everything on the trailer works.  I went out and bought a new controller, and the same thing is happening with it....no brakes.  Does anybody have any ideas?   I never installed a fuse under the hood, but I did have brakes.  I could even lock up the trailer tires if I wanted to!  Any help would be appreciated.

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: MrBill on 05/11/03 08:08 AM
Where do I start.

Lots of things can go wrong.
First I would start by checking all the fuses. I know which one? Well i do not have the layout, maybe SS can help.
Second I would look at the wires under your trailer for the brakes. I had one that was loose and I lost all the brakes on the trailer. Remember to make sure the contacts are clean. As for the trailer plug, I would use a test light to see if there is power to the plug. If there is power to the plug then your fuses are good. I would then look at the wiring on the trailer. Pull the wheels of the trailer and look at the wires by the brakes.

Well I hope this helps. I know it can be a pain, but you have to go on with a plan of attack.

Sorry i wrote this quick because i am leaving on a trip.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: Wiki on 05/11/03 08:38 AM
Well, I pulled the emergency pin out of the battery on the trailer and the brakes did lock up like they are suppose to.  That leads me to believe that everything on the trailer is fine as far as brake wire connections.  My question is would I get power to the controller and NOT the trailer brakes if a fuse were blown?  I never installed a fuse, but had brakes before!!

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: scubajeff on 05/11/03 09:56 AM
Check the fuses. I believe there is one under the hood in the fuse box that has a major role with towing. I had a similar problem last week. Found out the metal pins (contacts) on the connector plug for the trailer were corroded (oxidized). I cut down a fine nail file to fit in the holes for the pins and used a q-tip and some rubbing alcohol to clean them. Once I did that all was well.
Hope this helps.

I will try this.  I looked at the pins and they did look a bit dirty for a new trailer.  The plug usually lays on the ground.  Thanks for the info.

Check the fuse for the tail and brake lights.  If it blows it will cause your problem.  I had a Tahoe that did that so often that I put a circuit breaker in that circuit instead of a fuse.

Post by: Wiki on 05/13/03 08:57 AM
Well, the AV checked out just fine.  Everything on her is where she should be and working.  By the way, you don't need a fuse in std#1 to get power for your brakes like was previously thought.  

I have a Haulmark trailer, and all connections are done with those crip style connectors that have the flap of plastic that folds over the crimp and locks.  I hope you know which ones I am talking about.  Well, Haulmark uses about 100 of these things on their trailer wire setup and after checking about 20 of them......crawling back out and checking the brakes......crawling back under.....back out.....back under.....I finally found the one that had the bad connection.  

One crimp....



One freaking crimp....

Oh well, at least I know how my entire trailer wire system is run from the battery to the tailight of the trailer :4:

Post by: kevare on 05/07/03 12:21 PM
This may get long, please bear with me.  I hooked up a Tekonsha Sentinal brake controller (I know I know,shoulda got the prodigy).  I then connected the trailer up to test the wiring and everything seemed to work.  I haven't towed yet.  Anyway, since then, the lights on the Tekonsha seemed to flash different when applying the brake.  I looked it up in the trouble shooting guide and it says that I either have a direct short, excessive current request, or poor ground connection to tow vehicles battery.  I've checked the wires to see if they came loose and they haven't.  

Another thing that I noticed is that the headlight switch will not turn to the off selection.  It will only go as far as auto.  The other headlight selections work fine.

I'm guessing I need to check the ground.  Dunno how.

Any guidance will be GREATLY appreciated.
Sincerely, lost.

Post by: kevare on 05/08/03 01:30 PM
Please skip the part in the prior note about the headlights.  That's how it is supposed to work.  Duh! :2:  I did redo one of the wire connections but it didn't help.  Also checked the fuses and they are ok.  I'll do more checking tomorrow.  Maybe Sat I'll try to trade the electronic brake in for a Prodigy.  Who knows.  

Any other ideas? ???

I originally received the 02 harness from the dealer and exchanged it for the 03 harness.  Found that out because it had the wrong fuse.

Also, the 02 harness had a brown plug in and the 03 has a white plug in.  The 03 has the correct fuse, but are the wires correct?

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: 2M3Bill on 05/09/03 08:35 AM
The difference between the pre 2003 and 2003 is the location of the light blue and brown wires.  Switch them and all is well.  That is the only difference that matters, the plugs are the same except for the color.  The fuses for the 2003 are "J case".   ;D

Thanks for the recommendations folks.  I ordered the Prodigy form Camping World.  Only $109 with the discount.

Now all I have to do is figure out how to change the pinout on the GM harness I ordered as well.  It's apparently different on the AV from standard.

Now all I have to do is figure out how to change the pinout on the GM harness I ordered as well.  It's apparently different on the AV from standard.

A brake controller harness should have come with your Av. It plugs in under the dash by the driver's left foot, there is a panel that needs to be removed to see the socket. The harness has a plug on one end, blunt cut wires on the other, and a tag that shows the wire colors and functions.

There is also a fuse attached to this harness which must be installed in the under-hood fuse block in order to feed electric brack power to the controller.

If you are not using that harness, you should at least be able to trace the wires back to the plug in order to see what wire is what.

If you don't have that harness, or need more info, let me know and I'll take a look at the shop manual later tonight. It should have the connector pinouts.

I bought a Reese digital unit for my Av. I haul a 4 place snowmobile trailer and really like the ability to dial in the amount of braking I want the trailer to do! It usually depends on how many sleds I haul. Also, I wired it into the console cubby hole that is above the Other worthless cubby hole with the door...It works good to store my wallet, but nothing else!
I then just cut a piece of wood to fill in the gap and hold the controller in place so it wouldn't flop or come out easily. In this way it is easily reached when I want to lock the brakes on the trailer and not the truck.

Note that the '03 trucks have not been getting the harness gratas from GM! Some guys do if you ask the dealer, but GM hasn't been providing them with all of the trucks, lately!

INote that the '03 trucks have not been getting the harness gratas from GM! Some guys do if you ask the dealer, but GM hasn't been providing them with all of the trucks, lately!

I thought it was part of the trailering package, which is standard on '02 and optional on '03. If that's true, it should be included with an '03 that has the factory hitch installed.

It doesn't make sense to break it up into two packages: hitch and harness. I would think that the cost of the harness has got to be low enough, that the costs associated with keeping track of, processing, and delivering individual options would be more than the cost of the harness!

Does anyone know for sure the story with '03? Is the harness supposed to be included with the trailer package? All I know for sure is that all '02 models are supposed to have the harness. Sadly, some of them have been missing on delivery, however.

I've had both a Draw-Tite 5100 Activator (timer based controller) and a Tekonsha Prodigy (proportional based controller).  I've towed using both my F150 and TrailBlazer.  Hands down the Tekonsha Prodigy wins.  The timer based controllers basically delay after you press the brake pedal before applying the trailer brakes, for me this meant feeling the jerky trailer all the time.  No such problems with the Tekonsha Prodigy at all.  Don't waste money buying a cheaper one if you plan on towing much at all.

As for Camping World, you can often beat their price.  I've seen their sales having the Tekonsha Prodigy for $120, or you can check out places like http://www.southwestwheel.com which has the Prodigy for $124 with free FexEx 2 Day shipping.

My '03 Av was delivered without the factory harness.  Went back into my salesguy, told him I wanted one as part of my HD Tow Package, and he said no problem.  He called Parts Dept, got me a harness at N/C.  Turned out to be a '02 harness ("Aren't they all the same?" - Parts guy).  Turns out that it's not included anymore in the tow package.

After installing it, testing it, and insisting it was wrong, they finally agreed to call GM.  Sure enough, GM was kind enough to swap TWO wires on the harness (Controller Illumination and Stop Switch, I believe).  And '02 harness will work if you swap the two wires.  Thre were no '03 harnesses at the dealerships in my area, so...it works fine if you swap the two!

That's what I thought that GM has stopped with the '03 harnesses.. :D:

My buddy bought an '03 silverado and I had trouble setting up his electric brakes too! RV dealer didnt know the change in the wiring and gave him the wrong harness, too!

I do know that GM has changed the electrical architecture in the '03 ck trucks. It matches more closely the way the Envoy/trailblazer run their electrical systems. GM is under overhead cost pressure, and this is one way to commonize some platforms. The problem is that the dealerships aren't always as informed as we would like them to be! Just make sure you have the RIGHT harness for the RIGHT truck!

I think it's one of the easiest to set up and it looks cool.

I mounted mine with 3M sticky tape within reach by my right knee.  One great thing about the Prodigy is you can mount it up to 70 degrees.  

If you ever have an emergency it's critical that you mount it in a place you can reach without stretching.

I have to agree, the Prodigy is the best brake controller I've ever used.

My '03 Av did not come with the harness, I had t purchase it from my dealer.  The harness comes with the fuse for the brakes plus a 7 pin to 4 pin plug in adapter.

The harness makes the whole deal plug and play and the prodigy will bolt right up under the dash to the pre-drilled holes under the steering column if you used the "plastic sleeve" mount that comes with the Prodigy.

This makes it very simple to remove and store the Prodigy when you're not towing if you'd like.

The discounts are Camping World discounts.  If you do any camping & or towing get a CW membership.  They let you Stack coupons and discounts - very cool.

Right now they are offering a $30 discount on the Prodigy and if you are a member you get an additional 10% so you can get the Prodigy for $105.10 delivered.  Membership is $20.

I have used up all my current coupons otherwise I could have sent you one for an additional 10%.  

Camping World / Braking (http://www.campingworld.com/browse/categories/index.cfm?deptID=5&catID=234&subOf=37)

If you are lucky enough to have one of their stores near you they also have member only sales like brown bag days.  You get an additional 10-15% on anything you can put in a brown paper bag they give you.  Last time they had it I stuffed over $600 retail in there and with all their discounts, coupons etc.. I walked out the door only spending $390.

I don't know the GM Part# but the option number is the Z82.  You can get a GM harness wired for a Prodigy at Rjays for about $9.00 +$7.00 shipping.  Very clean install no wire fastners.  You will need to buy a fuse as well.

I'm a big fan of the Prodigy.  I have it mounted right where you have yours, Rondo.  :1:

My only complaint with the system, is that it gets glitchy on me when I'm in stop-and-go traffic, on hills.

Going up, it's snatchy and you have to power back.

Going down, it's soft and you need to add power.

Other than that, it rocks a fat one.

Post by: Y-Guy on 01/12/03 02:22 PM
I mounted my Prodigy on the lower dash just above my right leg, using industrial Velcro for now.  I wanted to make sure I like that spot first.  I used the sleeve and Velcroed it in place then ran the wire and slipped in the prodigy.  Its a bit heavy and sags a bit, but once I tow with it and know its right I'll screw it in place.  It's an easy reach to the manual controller and I can quickly see the settings while driving.  I didn't want to lean far to activate.

As for the jerkiness, do you have the Boost settings on? In town I turn it off, on the Highway I put on the first setting.  Its very smooth braking.

  The 2003 doesn't come with the harness, no matter what package you bought.  I couldn't even get my dealer to throw one in.  If you have a 2002 & are missing it, look in the glove box & even under back seats.   I heard of others finding them there.   Yes you can use a 2002 on a 2003 with just a couple simple wire changes.  I saw it in anothet thread in this section.
I nice 2002 owner who doesn't tow is going to give me his harness.  Must be a "cost saver for GM".  Kindof like not putting on a under the hood light on the 2003'3.  Talk about cheap! Spend over 30K on a vehical & they take off a 50 cent light.  I still love my AV & wouldn't trade it for nothing.
Can't wait for nice weather so I can actually try this AV out on the trailer!!!  Camping here we come!

I'm getting ready to put an electric brake controller into my AV. I have a 2003 AV 2500. It has the factory trailer hitch with the 7 way round plug.

I read all of the previous posts but am not sure exactly what I have to buy. I didn't get a separate harness for the brake controller, which I read that the 2003's did not have them included with the vehicle.

I think I will be getting the Tekonsha Prodigy since it looks like most people like that one the best. I'm looking for the cheapest place to buy it and whatever else I have to get.

I like that harness that plugs into the prodigy and then to the main connector in the truck. Do I need another harness going to my 7 way round plug or is that wiring already in place.

Also, my trailers are all wired to match the pinouts on my 2000 Silverado 1500 that has the 7 way round plug also. Do I have to switch any wires around on the plug on my AV to match the pinouts on my Silverado and my trailers?

All you should need is the wiring to go between the controller, and the socket that is down by the driver's left foot. This harness is model year specific - the 2002 and 2003 plugs have different pinouts. :6:

The rest of the wiring back to the trailer is in place, no additional harnesses should be necessary. Also, the pinout of the 7 way round plug in back is an industry standard - you should be able to plug in your trailer with no other changes.

The only other thing you may need to do is add a proper fuse to the under-hood fuse block in order to supply power to the controller for the brakes. I don't know which fuse this is for the 2003, as it is likely different than the 2002 with which I am familliar. It is also possible that you will have to add another fuse under the hood to supply auxiliary unswitched power to the 7 way round connector in back, but that came already installed in my 2002.

Does anybody have the proper fuse information for 2003?

 Medicboot,
 I got this from another post, I haven't tried it yet.  "If you use a 2002 harness it is OK but, YOU MUST MOVE THE RED WIRE FROM THE LOWER LEFT SOCKET TO THE UPPER RIGHT SOCKET IN THE WIRING PLUG. Otherwise the trailer brakes come on when you turn on the running lights and not when you push the brake."

Post by: disneydaddy on 04/16/03 09:15 AM
The harness for the 03 is GM #15085418. It comes with a "PAL" type 40A fuse and the 7to4 adapter. The harness plugs into the block under the steering wheel. The ones I have done have all plugged into the port to the right on the top row.
On the 03 all you need to do is install the supplied fuse in the port with the red plug marked "B+"
That will supply the 12v to your tariler for the breakaway and your battery.
hope that helps

If you have a 2002, it should have come with the harness standard. That harness will just plug straight in, and there should be no need to make any modifications. Simply follow the color code on the harness tag, splice wires to your controller as required, and plug it in.

The only time that the red wire in the harness should need to be moved is if you are trying to use a 2002 harness in a 2003 truck.

As for controllers, I'll defer that to someone with more experience with them. However, while I have no experience with it, the Prodigy seems to be a favorite (there is a link to it in the first post of this thread.)

Ok, so I got the Prodigy and it kept going out of adjustment. Would work to premature, then not activate. I took it back to camping world and they asked me if I have a Cell phone that was near it. I have my Cell in a Hands-Free system very near to the brake controller. Dealer told me to go one step down to the next controller, tried that and it works like a charm. Is this common or just my truck being "Unique" as always?  ::)

I just bought a new 2003 3/4 ton with the 8.1 liter engine, my trailer weighs over 6000 lbs loaded.  I had the dealer install a brake controller. Out of ignorance and blind faith, I assumed they would install a state of the art high tech model.  What I got was a Reese Brakeman. It seems to me there is a severe saftey issue with that model. It has a little thumb wheel where you can dial up the amount of brake you want to apply.  My concern is that if I had to make an emergency stop on the highway, I wont have the luxury of time to dial the mickey mouse little dial up to 10!  I shudder to think what would happen if I locked up the wheels on the Avalance but had a three ton trailer pushing my back bumper with it's brakes barely on.  Am I overreacting here or is my concern legitimate?  I think I may throw out the Reese and replace it with the Prodigy.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: AVid on 04/28/03 10:39 AM
Hey welcome to the club kevinl33.

You are right to toss the Reese. It is a time based controller. I believe the Drawtite is also. When you step on the brakes, the longer the brakes are applied, the more current is applied to the trailer. Not good in a "panic" stop. All the Tekonsha controllers are inertial controllers with the Prodigy being the most advanced. If you slam on your brakes the Prodigy will deliver max power to your trailer. (if it is properly adjusted).  :)

Post by: MrandMrsBurton on 04/29/03 03:08 AM
When I bought my '02 Av, it didn't come with the harness. The dealership told me that GM did a survey and found that owners of previous models of trucks weren't using the harness, so GM decided not to include it with the AV's. I told him I needed one and he went out to the used car lot and pulled one out of the glove box of a 2000 Silverado and gave it to me. I guess it helps to have friends at the dealership, cause I sure wasn't going to pay $40.00 for 5 wires and a plastic plug. The wire harness worked perfectly. I use a Voyager electric brake box and pull a tandem axle flatbed car hauler with my '69 El Camino on it. No problems at all.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: openminds on 04/29/03 09:08 AM
I will have to agree with AVid, toss the Reese. Time based controllers IMHO are garbage.

By the way, I finally got through to Tek's Tech line and they said that they have had problems with the Prodigy acting buggy with the following in the vehicle though NOT always:

1. Cell Phones
2. Amatuer Radio equipment and CBs
3. Laptop Computers

THAT was not in the brochure. But I will admit, they were very friendly and were ready to work with me if I still had the Prodigy.

I just installed a Prodigy brake controller on my '03 Z66 (with Z-82 package) and without installing a fuse of any kind there is power to the brake controller.  

Is this different than the circuit feeding the trailer plug?

Do I need to install a MaxiFuse?  If so, what is a MaxiFuse and where does it go?

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: midlifecrisis on 03/05/02 03:58 AM
I removed the trailer brake controller from my previous vehicle, and I've looked over the brake controller harness currently residing in one of my saddle storage box.  I've reviewed the owner's manual and it gives no instructions as to how to install it, only to tell me to see the dealer.

Has anybody here installed the harness and a brake controller?  I saw in the console topic that someone had their controller stored there when not in use.  I'm thinking this can't be that difficult.  The hardest part is probably mounting the controller somewhere under the dash.  Unfortunately, the Av has the emergency brake release lever in the place that I had the trailer brake controller attached in my previous vehicle.

I want to install this myself, because I don't want the dealer to do it, and the RV place probably hasn't had any experience with the Av since it is so new.  Any guidance would be appreciated!

I installed mine two weeks ago. It is real easy. under the drivers dash is the plug for the wire. Just plug it in and connect the wiring to the brake controller. Need you documentation from the brake controller. The documentation from the harness is on the harness. One other note! you will have to insert a fuse in the engine compartment fuse box. I forgot the name but you will see it. Is says trailer or trbrake or something like that. I sounds harder than it is. It only took me 5 minutes or less. I mounted mine right on the lower dash just above the gas pedel right next to the console.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: midlifecrisis on 03/05/02 05:37 AM
Thank you Mr. Bill!  I appreciate the info and will attempt the project this weekend.  Although the documentation on my brake controller is long gone, I did tag each wire before I disconnected it from my prior vehicle, so hopefully that will help.

I thought the plug under the dash was for the mechanic to plug in the computer to read codes.  Is that located somewhere else?

Does your shin or foot ever hit the brake controller where you placed it above the gas pedal?

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: ehahn on 03/05/02 05:42 AM
Hi mid,

I installed a brake controller a couple weeks ago - it was fairly straightforward - the wiring is exactly the same as a Suburban or Silverado.

Here's how to decode the labels on the accessory wiring harness:

1) "Fuse B+" (red, heavy gauge) = +12V (duh)

2) "Brk Gnd" (black, med gauge) = ground (duh)

3) "Brk Sig" (light blue, med gauge) = brake signal (goes +12V when the brake is depressed)

4) "Brk Out" (blue, heavy gauge) = output from controller to brake (i.e., makes the rear trailer hitch connector brake pin active)

5) "Illum" (brown, med gauge) is for faceplate lighting which dims with the instrument cluster lights - I don't need it on my controller.

Anyways, the other end of the connector on the harness plugs into the "convenience" block in the driver's foot well on the left side - it's covered by a black plastic cover with a hand-tightening plastic hex nut.  Removing the cover, you can use the "map" on the back of the cover to find the right connector to snap into (IIRC, it's on the top row, second from the left side - but verify before plugging in).

The fuse goes in the underhood fusebox - at "STUD A" - the leftmost unused slot.

I've mounted mine on the right side, mirror image of the brake-release handle.  I drilled into the colored part of the lower dash - which is still invisible unless you stick your head into the footwell.  No problems hitting my shin here.

Finally, the harness has about three feet too much wire length to it, so I just clipped it to a more appropriate length.

Hope this helps,
ed

I have a trailer with surge brakes. Instead of the typical
4 wire harness of gnd, lb, rb, brk....I have on the boat
a 5 wire harness. The extra wire is a back-up light wire, which allows for the surge brakes to disconnect when the AV and boat in tow are going in reverse.

My '95 Tahoe had the extra wire taped up in the wire harness and all I had to do was go buy a 5 wire plug
and hook it up, which then mated to the boat fine.

Since, the plug that was in the center console is only a 4 wire...has anyone been to the dealer for a 5 wire plug
or done something else to incorporate that back-up light wire into their existing 4 wire plug?

I installed a brake controller a few months ago right after I bought my AV.  Just as everyone else has mentioned, the process is a sinch.  Just follow the directions that Bill and Ed mentioned and you'll be fine.  I installed mine on the dash right in front of my right knee.  You may want to install a switch so you can turn off the controller when not in use.  It also helps when backing up the trailer.

Thanks to everyone's info, I installed the brake controller last weekend and everything works well.  I even hooked up the wires with quick-connectors, so that I can remove the controller from the truck when I'm not towing.  With the bench seat model, I can lay the controller under the dash between the two front seats on the carpeted floor area, secured with velcro.  If that doesn't work for some reason, I can always mount it permanently.

******UPDATED******
I have a 2003 2500 with the tow package (optional in 2003).  It has a 30A fuse in the engine fuse block Stud #2 which the owners manual says is for the trailor brake, so I didn't have to install a fuse.  The trailor guy says this is OK even though the brake controller owners manual says use 20A.
Also, there was no brake controller harness with the vehicle.  They don't come with the 2003's.
All I had to do is wire the brake controller harness to the brake controller and plug it into the convienience block under the dash, second from the left on the top. (And bolt and adjust the brake controller.) :)  
The problem I had was that I used a 2002 harness. NOW PAY ATTENTION. If you use a 2002 harness it is OK but, YOU MUST MOVE THE RED WIRE FROM THE LOWER LEFT SOCKET TO THE UPPER RIGHT SOCKET IN THE WIRING PLUG. Otherwise the trailer brakes come on when you turn on the running lights and not when you push the brake. :o

I have a flat 5 on my boat trailer as well. What I did was go down to the local muffler and hitch shop, they took my "round 7 to flat four adaptor" that came with the truck and gave me a brand new "round 7 to flat 5 adaptor".  The truck is all wired up to work for the flat 5, just plug and play.

Most places are reasonable about this stuff, my buddy recommended that I ask someone to trade and low and behold it worked. If you cannot find one on trade, they only cost about 5 bucks or something. Hope this helps.

8)  Like most people who will tow with their truck, I have installed a controller for the electric brakes on my race car hauler. Car (94 Camaro) and trailer are likely around 5000 lbs. If you have opened your glove compartment, you know GM gave you part of the installation harness. The rest of it will come with the electronic controller. I bought a unit built by Tekonsha Towing Systems, of Tokonsha, MI. I purchased it locally from an RV dealer. Most units are the same shape. I have seen brake units mounted via a U-bracket under the dash. While functional, that looks ugly and half-done. On my OnStar equipped Avalanche, I removed the two blanking plates directly beneath the OnStar plate, modified the holder by removing the center divider, (Actually, I bought a new one and modified that one), and mounted the Brake Controller with the front just sticking out enough to use the mechanical actuator and the sliding controls. It looks much better than hung underneath, is easily reachable for the driver, and, with the wire routed underneath and plugged into the stock fuse box, is almost completely hidden.  Trick! 8)

I'm plannign on hauling a travel trailer, probably about 75% of the towing rating of the 2500.  I know I'll need an equalizing hitch.  Will I need to replace the receiver with something beefier?

So many questions, so many experts to answer.  :)

Thanks for the site info - just ordered a Tekonsha Prodigy and harness. Free shipping and no tax - seems like a good deal.

I spent my summers during high school and collage installing hitches, wiring and brake controllers at my Dad's RV shop (years ago).

It will be interesting to see how the new all electronic controllers install and work (the brake controllers that I worked on all tapped into the tow vehicle's hydraulic line at the master cylinder).  Thanks again...Jim

Here's the pics of my Tekonsha Prodigy installed. The Prodigy unit has the mountable pocket so that you can easily remove the unit during non use. The pocket has two holes in the top for mounting. The manual says to mount it with the provided screws, which means you have to put holes in the dash. Because the unit has to be level and I didn't want to put holes in my dash I looked all around underneath for a mounting location. I noticed under the dash to the right of the brake release and under the steering wheel column there were two holes in the metal dash frame. I matched the holes in the controller pocket with these two holes, and to my surprise they came as a close match. ;D
I went to the hardware store and purchased 2 nuts, bolts and washers similar in diameter to the supplied screws but I made the bolts longer so that they would be easy to reach. The two washers were for under the dash for the nuts, the heads of the bolts were fine.
The location is easy to reach, easy to view, easy to install and is level both vertically and horizontally. Installing the pocket with the nuts, bolts and purchased wiring harness took about 20 minutes.

Problem need help, ( I also posted this in the problem area, I really need to solve this)

I was hooking up my electric brake controller, no problems, until I touched the cable leads to the metal brake arm.  Total accident because I was just setting the cable down.

Here is the sequence of events:
Hooked up the Av Trailer Wire Harness
Trimmed the ends to match it to the Prodigy
I followed the directions on the Prodigy to match up the wires
Before making the final connections I made just twisted them
Hooked up the controller, all worked great
Unhooked the wires and measured to trim them
Trimmed the wires and mounted the brackets
I went to hook up the new wires trimmed that is when I bummed the hot lead on the brake pedal.  It sparked.
I went to check to make sure the fuses were ok and they are fine
Went to hook up the controller and nothing no power.

I thought the controller somehow got fried, even though it was not hooked up so I went to exchange it, which they did, hooked up the new and nothing.

What do I do, I have tried everything, am I missing a fuse, I check inside the main fuse box, the one inside the driver door, had OnStar do a computer check, and nothing.  Am I over looking something, could have the power block under the dash been damaged in any way?

Helppppppppppppp if you can.

Thanks
Dennis

Sounds like the prodigy is you guys favorite but $125 is kind of high. What other Tekonsha enertia controllers work good? I only trailer once a month to the local Autocross and only tow 4500 lbs at most. I would get another brakemate but it would lock the trailer brakes up when the trailer was empty.

I tow my camper once maybe twice a month during the summer and fall seasons. I'm really glad that I spent the extra few dollars on the Prodigy. I'll have the Av for the next 5 years, and the camper for at least that same amount of time, so the cost of the Prodigy will pay off especially with it's ease of use and functionality. ;)

I'm leaning towards a Tekonsha Prodigy.  The other one I hear a lot about is the  Jordan 2020 Ultima.  I'm sort of looking for feedback on either model.

I have a Tekonsha Prodigy & love it. Easy to mount/connect & adjust. Also works well enough that the braking action with my 7500# enclosed car hauler is indistinguishable from normal driving. Longer stop distances of course, but no surging or lurching. Brain seems well suited to the job at hand.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: BruceCr_ms on 06/25/02 08:05 AM
My vote - Prodigy.  We just purchased a trailer.  After researching controllers, this one seemed the best.  Handles up to two axles, self adjusting (turning on and for hills), smooth operation, self diagnostics, and cool feedback (voltage being applied to the trailer brakes).  When I've rented trailers, the guys hooking things up ooh and ahhh at the thing.  Of course, it is just a piece of technology (heh, let go of my PocketPC before I hurt someone!).

Thanks for the info. I had  heck of a time finding where to plug the harness (part #3015) for my Prodigy into. I kept thinking I had the wrong harness since there is a plug above the parking brake and I thought I had the wrong adapter. I now think that plug is for engine diagnostics.

The box you're talking about is the closer to the firewall and the nut is a fairly large plastic nut that can be unscrewed by hand. My 03 AV had the plug location noted on the inside of the cover.

I've been reading through this forum on brake controllers and it seems to be that the Prodigy is the hands on favorite for electric brake controllers.  My question is this:  If I buy the Prodigy and the #3025 cable then I no longer use the harness that came with the truck?  Just install the Prodigy under the dash, hook it up to the adapter and install the 40 amp fuse under hood?

If someone would please clarify this for me I'd surely appreciate it.

Thanks!

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: AVid on 08/04/03 01:03 PM
Thats true...you won't need the harness that came with your truck. The 40 amp maxi-fuse is for the battery charge circuit for the trailer, your trailer brake controller fuse is already installed.

The #3025 harness has a plug on both ends, one plugs into the controller and the other into your truck.  :B:

I just saw that I was the first to post on this topic, way back a year and a half ago!

Today I will be leaving to camp this weekend.  I will be plugging in my brake controller using the plugs that someone suggested.  It has worked fabulously, since I can take the controller out and store it in the garage when I'm not towing.  While towing, the controller sits on the floor in front of the middle seat.  I don't ever bang my knee on it, and I didn't have to try and mount it anywhere.  And the mod only cost me a few bucks from a hardware store!

Just wanted to thank everyone again for all their help on this topic and let you know I'm still a happy camper!   ;D
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: PUNISHER on 11/05/03 03:18 PM
Another route to go is to tow it without the trailer breaks. I've towed this with my Z-71 with no problems. Go slow[er] and easy. Sure it takes longer to stop but nothing unreasonable. I went about 75mi with it. A double Axel trailer with just correct hit of tung weight, she will do fine. If she sways side to side move the bobcat fwd.

 example [not a real example]

sway at 40 move weight fwd 1 foot
sway at 55 move weight  fwd 6 inches
sway at 75 kiss, ass good by  :4:

If you plan to tow allot, by all means get equipped.

   when i was convoying down to the Savannah GTG we saw a guy towing a U-Haul.  that thing was swaying all over the road.  we got past him fast.  people amaze me sometimes.  you would think they would slow down.

The harness from a 2002 Avy will not work on a 2004 without modification.  I burnt my controller up a few week ago.  I was told the harnesss was interchangable by a trailer service center, but after installation we smelled smoke in the cab the break controller quit working.

Upon installation of the new control we discovered the brake lite and ground terminals on the '04 were switched from the '02 positions. :8:

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: msheldon on 01/01/04 05:39 PM
I finally got off my lazy rear and installed my brake controller, a Jordan Ultima 2020,  into the Av. It fits very nicely into the blank space to the left of the steering wheel, next to the A/C vent. My concern was whether the actuator cable would be long enough, but it reached all the way to the brake pedal with a couple of inches to spare.

I used the GM harness to wire it up, ended up cutting most of it off since the distance was so short. Question is, it came with a fuse, but I can't figure out what it's for. There's already power to the harness...

I've been very happy with the Jordan controller. It actuates using a cable to the brake pedal, thus the harder I hit the brakes, the harder the trailer brakes go, regardless of "inertia". Also, I had this controller in a Suburban before I traded it in on the Av. In the 'burb, the brake line run was very short, so I had cut the cable. When I realized I needed the full length for the Av, I sent it back to Jordan to have the cable replaced. They sent it back priority mail, no charge for the postage or for the work.

That fuse is intended to go into the Stud 1 location of the under-hood electrical center. It is not needed for the brakes, but supplies power to the unswitched B+ battery voltage on the trailer plug. So, if your trailer is wired up to charge on-board batteries while towing, or you have other accessories that need this battery power through the trailer plug, then you want that fuse installed. Otherwise, it is not generally needed unless you have wired other accessories (such as auxiliary lighting) to the Stud 1 connection.

Hehe, a half-hour after I posted that, I came across a thread on another board about someone's trailer batteries not charging. Wanna guess what the problem was? :) Sure enough I went out with my multi-meter, no current across the full-time positive. Found the fuse position, plugged it in, line is now hot.

The confusing part is that the fuse is provided with the brake harness, but in fact has nothing to do with the brakes...

Thanks for the confirmation.

Yeah, that threw me for a while, also. For the first year that I was here, I was always confusing Stud1 and Stud2 in my posts, and telling everyone the wrong thing, since I assumed that the stud mentioned in the trailer brake harness was the one associated with the brakes. ::)

But noooooo, it can't be that simple! Stud2 powers the brakes, and that fuse comes installed at the factory. Stud1 powers the trailer battery connection, and that fuse comes with the trailer brake harness. :2:

Go figure. :P

Don't try to cut the harness all at once. You will create a direct short and pop the 30A fuse. I have been trying all night to figure out why mine is not working after installing it.

It may or may not have the brake controller harness with it (probably not). The '03 did not come with it, you have to purchase it separately from a GM parts dealer. The harness has a plug that fits into a block behind the parking brake on one end, and bare wires on the other that you splice to your controller. Be *very* careful that you get the '02 harness, not the '03 or later. The plugs are the same, but the wiring pattern is different (bloody stupid). The harness also comes with a fuse, which is for the full-time hot wire to the trailer harness (goes in the block under the hood). You will need this if you are towing a trailer that has its own batteries that need charging while you tow.

AFAIK, GM does not have their own brake controller, so that's not an issue.

DON'T DO IT!  I burnt up my brake controller because the '02 model harness was different than the '04.  The '03 may be the same but it's not worth the risk.  From '02 to '04 Mr. Goofwrench switch the power terminal with the ground.  My unit went up in smoke.

Anyways, the other end of the connector on the harness plugs into the "convenience" block in the driver's foot well on the left side - it's covered by a black plastic cover with a hand-tightening plastic hex nut.  Removing the cover, you can use the "map" on the back of the cover to find the right connector to snap into (IIRC, it's on the top row, second from the left side - but verify before plugging in).

Hope this helps,

What to you put on the ends of the wires when putting them into the convenience block, 1/4" male spade terminal, just the bare wire or something else?

Ughhhh, So I read adn re read this entire thread over two days.
I went to GM dealer today- BOught my 2004 wire harness for 27 including tax.
So, I installed my Voyager Brake Controller (it came with my new trailer I bought) adn went FINE. ;D
Nice install, clean neat and pretty simple.
BUT- I have the 40 amp fuse left over.
Iopend my hood, poped the fuse box cover (2004, Z-71, 1500 series truck) adn saw this little RED block in a fuse cavity= it says B+ on it.
I pulled it out (it was just sitting in there not really connected to anything) adn looked in it's hole adn tried to put the 40 amp fuse I have left over. It/there is nothing to plug it into-
Am I to understand the 2004 model DOESN't need this fuse.

Goal-
Have brake controller that works
Have power to item being towed for a trickle charge on my camper battery while hooked to AV?

Some one please let me kow as I am picking up my trailer tomorrow adn I do not want the RV dealer messing with my baby.

HELP please  :o

I just answered your question on the NEO thread, but said you probably don't need constant power to the trailer. But this proves me wrong.

Unless they drastically changed things for 2004, you need to plug that 40A fuse into the STUD 1 location if you want the power pin on the trailer plug to be on. There must be a way to plug it in. Look in your owner's manual, and there is a picture of the fuse block, so you can make sure you're looking in the right place. It should be rather symmetrical with the 30A STUD 1 fuse, just on the opposite side.

I got my prodigy controller connected and mounted thx to you guys.   :1:

One thing I don't get is why the prodigy doesn't have an "off" position on the switch.  I had assumed the rotary on the left of the face would dial down and click off, like an old hand held radio.  But it looks like it hard wires in and sits there with the led's on forever.  

I would like to leave it under the dash all year but I don't want it powered on 24/7.  I will have to disconnect the harness when not in use.  I guess I should go read some more before I start griping.......   all else fails --read the instructions -- search the forum.

Did this mod today  :B:

I have a 2004 WBH Z-71 with the Factory Towing Option.

Included when I bought the truck was the harness (which I had no clue what the hell it was for...)
(http://www.retrorelics.net/jim/Boards/GMHarness.JPG)
The fuse everyone is talking about was wrapped in that Trailer B +Fuse plastic (lower left of photo) and taped to the harness.

Just like everyone said, Chevy did not install it the 40 amp fuse, it had a red plug in its place.

Here is the Fuse panel opened up under the hood.
(http://www.retrorelics.net/jim/Boards/40ampfuse.JPG)

The Red Plug gets replaced with the Green 40 amp Fuse supplied with the factory wiring harness.

Took the advice of this Post and went with a Prodigy, got mine from U-Haul, all the trailer shops and Auto parts stores did not have the Prodigy, U-haul had em and confirmed that Prodigy was the best controller on the market, paid $149 + Tax.

Here is the kit and its contents.
(http://www.retrorelics.net/jim/Boards/prodigy%20kit.JPG)
Included two mounting brackets, a soft cover for storing the controller when not in use, and assorted screws/wire splices and a harness.

Spent some time on the mounting, here is what I came up with. This is the "Concept" shot before I got into actual "fitting".
(http://www.retrorelics.net/jim/Boards/bracket1.JPG)

Here is what it evolved to, I used the double sided sticky tape as an insulator to reduce rattling or rubbing. Note I had to flatten the angle on the bracket from the origional "Concept" photo, also had to trim the sheet metal screw ends, and cut out the center part to allow the panel to fit back in place.

All mounting holes hidden on the back side of the panel.

The Factory harness, plugs in at a panel on the engine firewall on the drivers side, just to the left of the brake pedal.

Controller had this decal on it. I followed the Decal instructions, after cross-checking the wiring diagram for the factory harness. I did not use the Brown wire on the factory harness.

and confirmed that Prodigy was the best controller on the market,

Best *inertial* controller on the market. There are certainly better controllers, the best of which interface directly into the vehicle's master brake cylinder (My father uses one of these). Those are much more expensive, and significantly more difficult to install, however.

My personal favorite is the Jordan controller. Inexpensive, and uses a direct actuator attached to the brake pedal rather than depending on the brake-light/inertia to operate. Also nice in that it shows the actual voltage going to the trailer brakes while under braking. If the voltage is abnormally low, this tells you that you have a problem with the trailer brakes.

   Thanks for your step - by - step pictures on the install. Set up the Prodigy this weekend using it as a guide on my 04.  Everything went smooth.  

   I used the two holes in the dash frame directly under the steering wheel.  Put two screws and wing nuts through these and the pocket holder.  Adjusted it then removed and put in the case and stored it until needed.

  Thanks again.

I switched to the BrakeSmart controller. I used the Prodigy for a few years and liked it, but I wanted something better. The install was the same as the Pridoigy except for the pressure sensor at the master cylinder. It is a true porportional controller. The smoothest I have ever owned.

You will need to splice the wires from the harness that came with your truck to the brake controller harness.   The Prodigy comes with connectors and directions.  Just follow the directions on the brake controller harness as to what wires go where.  It's not intutive so read the directions.  I just did this last week.  Pulled my trailer this weekend with no problems.  The harness that came with your truck plugs in under the dash.  My 05 has a black screw on cover over the connector box.  The owners manual shows where to plug the trailer wiring harness in.  It only goes one place, one way.

not to change the current topic too much, but...

just purchased the Prodigy brake controller, started installing it, and noticed previous in this thread you guys talk about not placing the Prodigy "too close" to an RF emitting product".  I have XM in my AV, the SkyFi unit which does emit a pretty strong RF frequency.  I was going to install the Prodigy underneath the steering wheel on the dashboard panel (where there are 2 holes for install).  Anyone have thoughts on whether I need to worry about XM's signal messing w/ the Prodigy unit? 
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: lifeisforfun2004 on 02/03/05 06:15 PM
Update to my previous question re: XM radio interferring w/ Prodigy brake controller.  I mounted the Prodigy under the steering wheel, turned on XM, and tested the XM signal strength by listening to a walkman on the same radio frequency that XM is dialed into.  Sure enough, I picked up the XM channels on my walkman all inside my AV's cabin, almost to the backseat!  I'm giving Tekonsha a call tomorrow, but does anyone have any experience on this?!?  I love listening to my XM, but not if it means the brake controller is going to fail and I plow into the guy ahead of me!  help!
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: AVid on 02/04/05 02:35 AM
I can't see where the brake controller has anything to do with your XM. It neither accepts nor emits any RF. Did you hook up your trailer and see if the brakes work?

Your Walkman will pick up the XM  SkiFi if the Prodigy is there or not. I used to have a CB mounted next to the controller. It surly emits more RF than the SkiFi. No problems.

I have never heard of such a thing.

Let us know how things turn out. Maybe I could learn something new.

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: lifeisforfun2004 on 02/04/05 06:07 AM
Thanks for the reply AVid -- "I can't see where the brake controller has anything to do with your XM. It neither accepts nor emits any RF"

I would agree too, and wouldn't worry about it, except that in the Prodigy instructions the first line reads, "Do not mount  or activate RF generating items (ex. cell phones, two way radios) near (less than 12 inches) the brake control."  My XM set up includes an RF modulator that takes the XM signal and changes it to an RF signal so that my radio tuned to 87.9 can pick up the RF signal. 

Openminds posted back in July of '02  (in this thread) "Ok, so I got the Prodigy and it kept going out of adjustment. Would work to premature, then not activate. I took it back to camping world and they asked me if I have a Cell phone that was near it. I have my Cell in a Hands-Free system very near to the brake controller. Dealer told me to go one step down to the next controller, tried that and it works like a charm."

So, I'm going to call Tekonsha today and see what their "official" line is re: RF emitting units is.    Again, I normally wouldn't worry so much abou this, but this'll be my first time ever pulling a toy hauler, and with so much weight behind me I don't want to find out that listening to AC/DC screwed w/ my brake controller and caused the trailer brakes to fail!  I'm glad to hear you had a CB mounted w/ no problems, that helps a little bit. 
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: lifeisforfun2004 on 02/04/05 06:50 AM
One other question I have while I wait for an engineer to call me back from Tekonsha...

How many of you have had to use the manual control on the Prodigy while hauling?  How often?  I ask because I may move it from where I have it now (directly below the steering wheel along the edge of the dash panel) to where it sounds like most people install it, aprox 5 inches to the right of where I have it.  I don't have a clear view of the front, and it would be difficult to control my vehicle AND grap for the Prodigy to dial in more brakes in a situation. 

Basically, is the Prodigy more of a "set and forget" controller that I may have to manually adjust every so often?  or will I constantly be reaching down to dial in more/less power?  Do I need a clear view of the front to see what the display is telling me?
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: AVid on 02/04/05 09:32 AM
The Prodigy is the best inertial controller out there. It is not the best overall. BrakeSmart and Jordan are top of the line. Those two are set and forget.

The Prodigy, once set up, does require that you sometimes adjust the boost. I found that I needed to up the boost to "3" while at highway speeds, and down to "1" in town. Once the gain is set, you can leave it alone.

I did once use the manual control. I hit the rest stop exit ramp a little too fast and had to stop a little faster. You don't need a clear view of the controller, but it's nice to know what it's doing.  The display tells you the amount of voltage transmitted to your brakes. Sometimes good to know.

Let me know what Tekonsha says. I use the BrakeSmart now, but my daughter still uses the Prodigy.

AVid
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: lifeisforfun2004 on 02/04/05 06:00 PM
I spoke w/ technical support and they said a couple times, "we recommend not to install the Prodigy controller near any RF frequency emitting products", but they wouldn't say why.  I finally got them to ask an engineer what the reason for this was.  I got a message back a couple hours later saying that the Prodigy controller was rated for "100 volts per meter" (?), and that if an RF frequency did interfer, it would cause the Prodigy controller to apply the trailer brakes.

I am going to pick up the toy hauler tomorrow, and I will do (a few) tests in a location w/out any traffic to see if I detect any interference.  I'll let you guys know what my experience is.   Thanks AVid for the replies, this is why I love CAFCNA!

My prodigy has worked flawless for at least a year now. I have never had the cell phone mess with it. The best thing I like about this unit is that it will let you know if the trailer cable is pluged in correctly or if it comes loose while you're underway. It also applys the trailer brakes harder as you slow down. Pretty cool! I got mine via buy-it now @ ebay from a trailer dealer.

Anyone have the Prodigy Brake Controller installed in a place other than under the dash? I like AVid's pic of the braksmart installation but I have the 40/20/40 front bench so no console. It's currently mounted under the dash, in front of the brake where the existing 2 holes are thanks to reading this forum. Problem being, I ran into a situation where it would have been nice to reach the manual lever and couldn't. I would like to mount it higher and in view, any suggestions, better yet, pics?

Mine is mounted as on the bar like most others. But I've thought about your problem. I seem to be able to reach mine just fine for the manual lever, but how about on the pad just above the bar either left or right side with some velcro? ???

I've got the Prodigy mounted in my 2003 Av in the left side of the cubbyhole just below the radio.  The whole box pops out of the dash, so mounting it on the bench is relatively easy.  It was a bear plugging in the wiring harness though, because this has to be done from the back after the box is reinstalled in the dash.  It makes for a clean look with about a third of the unit sticking out, easy to reach, and no holes to drill in the dash.  If the Prodigy is taken out, then one can purchase a new insert into the dash, and there will be no evidence that one was ever there.

Sorry, no pictures though.  I hope this helps ::)
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: RaeDar on 04/06/05 03:27 PM
Thanks to pbmartin and AVid. If I understand pbmartin you put in in the whole to the "right" of the radio? I don't have onstar so that is one big open hole. I did consider that but it was cold when I installed it and I didn't want to tear apart the dash just to find out that that box wouldn't seperate without destruction. If the rear of that box didn't narrow, I wouldn't even have to tear it out. I think that is what I will end up doing. Either that or go see if the junk yard has a middle console from an Avi or Silverado, I'm thinking all I would have to do is remove the cup holder from the bench to make the console fit? Thanks again!
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: pbmartin on 04/08/05 04:45 AM
RaeDar,

I do not have OnStar either, and there is a square hole to the right of the radio.  There is also a large rectangular opening below the radio.  This is where I put the Prodigy, on the left side.  Itr still leaves some room to put stuff on the right side.  It looks like it belongs there, and is easily accessable and viewable.  This box does come out.  You will have to make a hole in back for the wires, and it needs to be large enough so that you can snap in the wiring connector from behind.  A bit of a challenge, but it can be done.  Hope this helps.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: RaeDar on 04/09/05 01:26 PM
pbmartin,

Thanks for your reply, I appreciate it but I do not have a large rectangular opening below the radio. The only thing that I can think of is you have the console. Below my radio is the heat/air controls and below that is the cigerette lighter/accessory plugs, below that-a panel that covers the area when the console would be. I think I am just going to go for the square hole on the right and see how that looks. Thanks again!

the brake controller with a backup light hook up is for hydraulic surge brakes .. there's a selenoid (sp?) in the surge brake assembly to allow a heavy boat/trailer to back up when normally back hydraulic pressure would be applied.  I"ll read the rest of the posts, hope I wasnt a bonehead and answering before reading.

You can also get a Drawtite GM wiring harness (18284) to use with the Prodigy, as the Tekonsha Prodigy and the Drawtite Intella Stop Ultra are the same. Simple plug and play in my 2004 and I believe it is the same for 2003 up to current models. A company by the name of http://www.cequentgroup.com/ owns almost everything to do with all hitch brands. I found on mine to use the factory holes under the dash that my foot hit the back of the controller so I fabricated a mount similar to the one it came with but moved the holes 1 1/2" forward and 1/4" up. My shoes don't hit so far. Have to try bigger boots later.

I know I'm going to get laughed at for this but, hey, I have next to "NO" knowledge on towing but I bought a Hopkins controller.   Anyway. . . anyone know why my brake lights are on and dont go off?  When I unplug the unit, everything works normally.   I wired this thing up as below.

does anyone have a picture or part # for the green 40a fuse that is needed in the 2003?  I know that it is the B+ trailering J-case fuse, but I want to see it so I know that I have the right one before I buy it. 

thanks for the help

As you should be able to see in the chart, the 40 amp J-Case fuse should be green. It should be shaped like the 60 amp in the picture.

Hi!!  I’m new here.  I hope some one can help me.  I have a 2003 Avalanche 1500.  I’m trying to hook up a trailer brake controller.  I have the harness that plugs in under the dash on the left side.  The instructions for the harness say to plug it in and check for power with a tester.  I did and have no power.  There is a fuse in the “STUD 2” position of the UBEC.  I have read elsewhere that there is a wire between the UBEC and the fender that needs to be connected to “STUD 2” to provide power to the brake control.  Is this true? What about “STUD1”, is this only for auxiliary power to the trailer or does it have something to do with the trailer brake circuit as well?

Thanks in advance!!

Post by: Leafangel on 02/08/08 06:22 AM
Ok after some further reading I think I have this figured out.  I do need to hook up the power under the hood.  I'll go home tonight and give it a shot.  My last tow vehicle was a Ford Excursion and the brake controller hook up on it was plug and play, to easy.  I wish GM would take some of their competitions ideas and put them to use!

Thanks again!!

On a 2003 there are no wires to hook up. That silly "feature" showed up on the 2007 GMT900 models. The fuse that has to be installed in yours is for the 12v feed to the trailer and has nothing to do with the trailer brakes. I suggest you pull the fuse in both stud positions and check them. I think you will find the one that supplies power to the controller is blown. Or...make doubly sure you have the right harness, they changed in 2003.

Hi guys, is the Prodigy controller still "the one" to get?  Any particular model?  It's time to get a controller and I want to get the best bang for the buck, the budget is $150 MAX, preferably more like $120 though.

Thanks for any tips...

In order..Prodigy...Prodigy P3...Tru Control (http://www.brake-controller.com/). The major difference between them is the software they use. All are based on an accelerometer chip. There are even better controllers out there but they are expensive.

OK, just got my 2008 Avalanche LTZ.  Great truck!  Also picked up a new trailer to go with it!  26' with a slide out.  At the RV dealership, the installer put in the new Prodigy controller (as per wiring schematic) then tested everything and nothing...  I called the dealer and they didn't know what could be wrong.  The manual says that custom wiring may need to be done under the hood as well.  How vague can they be? ..  Hmmm.  So eventually the guy looking under the fuse black box under the hood sees a cable not connected.  He connects it to the bolt on the front of the black box.  Still nothing.  Then he notices a second cable disconnected.  He connects it and away we go.  The point is, that the LTZ comes with HD trailer package and is disconnected under the hood and they don't have the decency to tell you where the wires are hid.  (Under the black box)  :E:.  It wasn't a big deal, but if I had to pay a guy to hook it all up it would have been 100-200 bucks if he was honest.  The cables were there with a loop on the end of each.  Just needed 2 nuts to attach them to the bolts.  What a farce.  Any how.  great truck great trailer!

There are many differing opinions on the subject, but from what I have read here in the previous 10 pgs of this thread is the Prodigy is the best bang for the buck.

I have been "getting by" with another brand analog brake controller since I bought the truck. I just ordered a Prodigy v2.6 from RVwholesalers (http://www.rvwholesalers.com/catalog/product.php?productid=60&cat=0&page=1) for $100 delivered.

Post by: UtahAV on 10/09/08 10:23 AM
It is on the fuse block, to the left of the brake pedal, under the dash on my 04. Depending on the brake controller you purchase, you may be able to pick up a plug-n-play harness to go with it. I use the Prodigy controller and purchased their harness to go with it. Plugged the harness to the connector on the AV, plugged the other end into the Prodigy brake controller and POOF, instant trailer brakes!  :thumbsup:

Hope this helps!

I know I've read this several times on here but... I have a 2008 Avalanche and tried to hook up a Hopkins Impulse Brake controller. Now the brakes on the trailer are always on and it ( i assume ) ran the battery down on the truck. Any suggestions as to what I need to look at? I wired the white to white, the black to red/black, the blue to light blue and the the red to dark blue. I hooked the two wires under the hood up and have power which maybe I suspect leads me to think the problem is at the seven way plug. Any thoughts on what I should be looking for or any thing else?     ???
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: cadboy1 on 09/20/09 02:11 PM
There is only one wire that brings electric to the brakes and if it was always on your trailer brakes would be locked up. Does your brake controller go off after 15 minutes or so of none use? Most do.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: nickynutts on 09/20/09 04:14 PM
I can't tell you if the controller goes off after 15 minutes or not. The trailer brakes are locked up and it got too late last night for me to continue so I stopped and waited until today. That's when I found my battery run down as the truck would'nt start! I have just unplugged the controller and will either start over tommorrow or I'll order the Valley controller that has a cord with it to match my truck. I'm about at my wits end and if it's not real obvious, I know very little about electric and such. lol :E:
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: motofixxer on 09/21/09 08:27 PM
If your trailer brakes are activating you can hear them humming if your near the wheels. So if your controller is hooked up, trailer is plugged in, and you can hear humming near trailer wheels when brake pedal of truck is not pressed. Then something is wired wrong. The hardest wire is the one going to the brake switch in truck. That could be wired to a hot lead, and causing trailer brakes to activate constantly, which might be causing the problem.

Yes, I kinda like the Avalanche . :needhug:

I have an 08 and had to hard wire (solder) the Prodigy pigtail to the GM installed wires located under the dash. My problem is that I have no power at the red/blk wire coming from the GM installed harness to power the Controller.  Some time back a guy had a similar problem with his 07 and stated there were 2 red wires under the hood that had to be connected to the 2 lugs located under the electrical box cover, lower front.

Does anyone know anything these wires. I just did the install today and then discovered I had no power coming from the factory harness.  :E:
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: CornBurner on 10/06/09 09:24 PM
Look under the hood on the driver's side at the fuse box.  You'll see two heavy guage wires under it at the front that each have a loop on them.  One gets hooked up to ground on the box the other to power.  The controller people should have known that, but my guys didn't either.  UGH.

Good luck

Title: Re: EVERYTHING Trailer Brake Controllers
Post by: motofixxer on 10/06/09 09:27 PM
Check to see if you need to add the fuse in the fuse box. Its a little red fuse plug\spacer that needs to be removed and replaced with a fuse. Available at like Autozone or something. I think it should be a 40a.
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: hollywood Av on 10/08/09 06:46 PM
You were right CornBurner. The wires even had the eyelets already on them which were sized to fit the different size lugs. I picked up a 30 amp Auto Reset circuit breaker today and plan on installing that somewhere in the line.  I didn't find a specific fuse for the brake wire but there are fuses for the trailer turn, running etc.  I guess that's why I've been told to install the circuit breaker.  Thanks for the info.

Hollywood, how exactly did you wire your harness to the wires that come out from under the dash? This is where I had 1 problem. Then when I thought I had them right and I hooked up the wires under the hood, I had constant power to the trailer brakes. Frustrating... at this point I just stopped till I get something I can work with and someone to hold my hand & tell me it'll be alright... lol :E:

I have new (2009) AV-LTZ 4X4, bought it 3 wks ago and installed a Hopkins Agility Electronic Brake Controller.  Did some heavy duty towing this weekend for the first time.  Had to wait for the 500 mile break-in.  Now that I have towed and loved the perfomance all around, it makes me even happier with my purchase.  It replaced an Expedition with a 5.4 lt.  Anyway my question is this:

Having trouble setting the desired percentage on the Brake controller cause as I step on the pedal, I only get a gradual increase on the digital read out.  The harder I step on the pedal the more stopping power I get.  I'm having no issues with stopping as I know how it feels when there's too much or too little brake control directed from the Brake Controller.  Just kinda want a warm fusy by someone telling me that an Agility Controller does just that (meaning low to high percentage readout) increasing the percentage on the controller the harder you press down the pedal.  Any help, advise or guidance would be greatly appreciated. 
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: hollywood Av on 11/19/09 06:31 PM
nickynutts,

My factory wires were clearly coded and shown in the owners manual.  Prodigy sent instructions with the controller which had the harness schematic so the connection was fairly simple or I just got lucky.  After confirming that everything worked I soldered and shrunk wrapped the pigtail connection under the dash.

I do not see a problem in your 10. Unfortunately, the recent avalanches do not come with a plug in ready to receive the controller. You will have to find the wires under the dash and connect with the connecting harness provided with the controller.

Do not forget to find the wires under the hood,close to the fuse box, otherwise, you will not have power to the controller.

I Tried to install a prodigy and thought things went well until I hooked up my trailer (a pop-up).  It didn't recognize the trailer as being connected.  My AV is 2002.
1) is there something about the wiring being wrong on the harness?
2) do I really have to under the hood and connect some wires to the battery?
3) Did I need to put the fuse in stud#1 (which I eventually did - no change)?
I want to camping in Yosemite tomorrow and my only other option is to have it professionally installed (ouch!).

Hopefully a simple question.  The 2010 Avalanche LT options list has a controller as an option, $200, is the consensus it is not worth buying or is it just a new item?  A lot of this thread focused on installing one of several after market controllers and how it is connected/placed rather than the Avalanche option controller. 
Thanks in advance, I hope to buy an Avalanche in March 2011 and am trying to get smart on which options to buy or not. ???

Depends on type that the dealer would be installing.  Like I said I got a Prodigy inertia for $116 and took me more time determining which drill bit to uses then it took to install.  If the dealer is going to install some cheap time delay then I would say no and buy the prodigy.

I was not sure as if you go to the Avalanche site, do a build, then click on the controller option (no number in build) it does show a picture.  I did not know this was a dealer choice/install item.  Thanks gunner65, that would be the model if I buy outside GM or if I get a choice.

I know this is sort of late, but I had the same issue.  It turnd out to be a Trailer issue, not a brake controller issue (I found both left side brakes were disconnected).   If you've checked your AV connections, start looking at the trailer.

Oh, and I installed the Tekonsha P3 (updated version of the Prodigy).  And have been nuttin but EXTREMELY SATISFIED with it.  I just towed my 5400 lb trailer 2400 miles and it ran GREAT.

It's not dealer installed it IS factory. It's a new item GM wasn't smart enough to offer before so very little info on the street about it. Should at least have a nice clean factory look, not something added on where it should be out of the way like aftermarket ones.

I would have gotten one on mine if it was available.

Yes you can get a plug n play cable for a 2002 Avalanche.  Look here etrailer, brake controllers (http://www.etrailer.com/bc-2002_Chevrolet_Avalanche.htm)<-- Link

The connector is under a plastic cover on the firewall between the brake pedal and the parking brake.  I don't remember the exact location in the set of connector under that cover. 

Be sure you get the 1999-2002 adapter.  If you get the 2003-2006 harness, at best it won't work, at worst something is going to smoke.
You might be able to find better prices then what is in the link I posted, that's just the first place I looked after googling trailer brake controller.

That's not actually a problem.  The brake lights should come on when you apply the brakes.  Using the manual override applies the trailer brakes. 

I just checked a different brand controller and it works that way too.  (I'm in a campground, they're everywhere.)

I was reading this section the other night and found this tag in my 02 Avalanche. It was attached to the controller harness, fuse and 7 to 4 adapter.

Is it possible to retrofit the factory brake controller to trucks not equipped with it from the factory?

I have a 2011AV. and have been trying to figure out how to hook up a controller, and have found that the wires should be bundled under the dash. If anyone knows anything else about this would you please let us know. Thanks mags :B:

Tekonsha Primus IQ Trailer Brake Controller - 1 to 3 Axles - Proportional
Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers - GM

Anyone with experience with this model? Etrailer.com has it on sale for $109 including the GM harness adapter so you don't have to splice the two together, just plug and play; only towing a large tent trailer, nothing too heavy.

Also confused on the 2002 12V supply, is it just install the fuse or hook up the wire and the fuse? It's a Z66 so it has the  factory towing package.

Don't know if this ever got answered.
I just put a P3 on my truck to pull a horse trailer.
I have the factory tow package and it came pre-wired for a brake controller.
Just had to replace the green block fuse to get 12V going to the rear.

Prior to my 03 AV I had a 93 Dodge D350 dually and it had a brake controller in it.  One thing that I noticed was that everytime I would hit the brakes the controller would light up.  So now I have my awesome 03 AV and it came with a brake controller (so I thought bonus)  but however whenever I hit the brakes the controller does not light up.  One thing I'm wondering is that when I bought the AV in 07 it was a GM Certified Used vehicle and I wonder if the dealer had to disable the controller in order to certify the vehicle.  This hasn't been a huge concern for me up until I started reading some threads through the forum.  We now have a pop up camper with no trailer brakes but I want to utilize the 12V system from the trailer plug to the camper.  Not to run things in the camper but to charge a battery for me while the vehicle is running.  I would like to get the controller working again for in the future I would like to either put trailer brakes on my pop up or when it comes time for a newer pop up or a bigger ATV trailer I might want one with brakes.  Thank you all in advance for your help with this.

Check the fuses under the hood there is a 30 amp and a 40 amp (1 for brakes and 1 for 12V).

From the factory there were dummy fuses in those spots, maybe the dealer returned them to factory.

So in the Stud 1 there was the red plastic plug.  So I pulled that threw in the maxi fuse for it and then went and checked the brake controller.  Nada still no activity light on the controller.  So next step I guess is to crawl under the dash and check the wiring harness to see if its plugged into the socket on the firewall.  If this doesn't do it then I guess that maybe the controller is bad?  I'll also have to check the wires and make sure that its getting power.  To be continued lol.

I'm the new owner of a 08 Black Avy, I've been considering getting a Toy Hauler to take the Old Ladies and my other play toys, a couple of Harley dressers on longer trips with. As I've been reading posts on here that have given me considerable info on towing capabilities but have a couple questions as to the posts on the trailer brakes…
I read early in the thread that there was a GM brake controller for the 03 is there one for the 08? If not is the Prodigy still the better one to get?
My preference is a plug and play set up.
Thanks in advance for any help. Jim

idbeast;
I have an '08 black Avy and I tow a 5K+lb (loaded) K-Z toy hauler for my Ultra and my wife's Chihuahua.  I have used a Tekonsha PRODIGY Brake Controller - Proportional for 4 years trouble free. I got mine from etrailer.com for around $100 four years ago.

On the 08 if you have the towing package the controller wires are under the dash but unless someone has already used one you will have to get the pigtail harness and wire it yourself. No biggie. I got mine with the controller. Once you attach the plug to the factory wires and the hot lead to the appropriate lug on the under-hood fuse box, it's pretty much plug & play.

Good luck with the tow hauler. I have a 3.73 rear with the towing package and ended up installing a supercharger for more pulling power.

Thank you for the reply Hollywood Av! I'm sorry I didn't respond sooner, I was waiting for the message board to send me an notification to a response, as I forgot where I posted this! :E: How is the supercharger working out for you? I'm one of the former owners of PulleyBoys, we made aftermarket pulleys!
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: JohnnieMo on 12/24/13 01:17 PM
I did the same thing as Hollywood - added the blower for more grunt.  It is quite a joy now.  However you are giving up something to get something.  The Av is an okay tow rig, but awesome at so many other things.  The blower makes it a pretty good tow rig, but the amount of fuel you burn is mind boggling. 

I refused to leave my Avy for a diesel, so this was the best case scenario.  Man it pulls hard now.  But you may need to upgrade some other things.

I also picked up a Prodigy P2 and wired it in.  However the boat I bought (afterwards) has surge brakes, so the controller was not needed.  If you do wire one in, I highly suggest soldering the wires.  It's just safer that way. BTW - my boat on the trailer is 6500lbs.

The harness label on my 2010 makes reference to a light blue wire with a white stripe, but no such wire exists.  There is, however, a green wire, that the diagram doesn't reference.  UGH.

I don't know if this is the right category to post this in or not, but I'm looking for ideas for a clean, low-profile installation of a trailer brake controller in my '04. Unfortunately, an integrated controller was never offered on the GMT800s like it was on the 900s. But there are several cubby holes on the dash that I think I could use. One is the slot between the two 12v outlets, and the other is the squarish cubby to the right of the radio and HVAC controls. My only concern with that one is it's a bit of a reach across the dash.

I'm not opposed to cutting into the dash panel as long as it doesn't look like a hack job. But I'd rather utilize the space I have. I saw one photo where someone put the controller in the square cubby. I'm leaning toward utilizing the slot between the 12v outlets, or cutting out a space just above it. Any photos, experiences or ideas would be appreciated. Thanks.

igotzzoom What brake controller are you thinking about.   ???
Title: Re: EVERYTHING Trailer Brake Controllers
Post by: igotzzoom on 01/17/17 11:54 AM
Looking at the Tekonsha Prodigy P3. It's one of the priciest, but seems to get consistently positive reviews. Also, as a follow-up to my last post, I can reach the square cubby to the right of the stereo and HVAC controls fine. I think that would be my optimal/preferred location. Not sure if the Prodigy will fit in that space. I don't mind if it protrudes a little.

I've been looking at this Hopkins controller mainly because you can mount the main unit down and out of the way and the slide switch close to you maybe next to the console so you don't have to reach for it and you could put the display in the cubby.

It's also allot cheaper and has good reviews.. Anybody have this one or used it?

I think this may be the one I saw on another thread somewhere on this forum that was mounted in the dash cubby. I've also wondered if the OE GMT900 controller could be put in the cubby, but realized there was no display for the gain. I wish someone made a slick integrated plug & play module to fit the GMT800 cubby hole.

No defiantly not the same one, The Hopkins slide switch and display are separate from the controller. You could mount the brake slide switch close to you so you don't have to reach across the truck for it. The display could be mounted on the dash, in the Cubby, on the console etc..

I bought a Primus IQ 90160 controller and the Tekonsha 3015-P harness. Super easy plug and play for my 2004 Z71.

There was one funny thing when I plugged the harness into the block under the dash: there was already a red wire attached to the upper right 'blade' in the block. I pulled it off, figuring it was something to do with the original trailer wiring. Well, that isn't the case.

I have a Viper remote start and the red wire has something to do with the control for it. I started the truck with the Viper but couldn't shut the engine off with the brake pedal (no key in ignition) or with the key in the ignition. The kill switch when opening the hood stopped the engine.

I started the engine again with the Viper and this time touched the previously disconnected red wire to the red wire on the controller harness. I just kind of forced the connector for the Viper wire into the controller harness red wire hole. (I hope that made sense). This time all the Viper controls worked correctly.

Do you think I can splice the Viper red wire to the controller red wire? Or maybe the better question is do you think I'll damage something it I try it?

Thanks for thinking about it.

Do a search "seo" with me as the poster, it will give you a idea where to move it.
 You don't want to double up on 1 wire.

Thanks for the help!! I'll hook my red Viper wire to the hot  plug in the Upfit cavity when I get home this afternoon.

This place is amazing.

Update: that didn't work. I got the same symptoms with the Viper. I tried all the open pins. I think the ones with 'always hot' always turn the truck on but I can't control it with the key. I'll play around more next weekend and see if I can figure out how the Viper is wired.

what model and brand controller do you have.

The 03-06 have a different wiring harness. So the controller should work but it is wired to the AV different on a 07.

FWIW, Best controller EVER!!  Pulling an 18' Sure-track car trailer and 3000# vehicle with a 2004 Z71 Avalanche that has the factory towing package.  Have brakes on both trailer axles and a 800# TW Fastway E2 hitch.  Zero sway - been up to 75mph (typically I tow at 65 mph) - tracks like a champ.  Slowing down is smooth and uneveantful - and I've never locked up a wheel, even when the trailer is empty.  Never had to do any adjustments from the factory settings on the controller.  Biggest problem I have is remembering the trailer is there.

Mounted in the left side of the lowest cubby underneath my radio in my 2004 - it's tiny!  Out of the way of everything but still sticks out enough to get at the manual brake function of the controller.  Had to lengthen the aftermarket jumper (to the brake controller connector) that I bought and run the wires through a hole I drilled in the back of the cubby.  Recognizes when trailer is plugged in and it turns itself on - otherwise keeps itself shut off.  Using 1 year so far.
