Well, your list looks good to me but they still owe me the mic! I hope someone can confirm your changer cable! Remember, I opted out on that goodie! And I was just given some contacts, so that won't help!! (I didn't need them anyway because of my circumstances...)

We love pic's here thanks for sharing them! I just didn't get the opportunity for providing any myself .`Just the avatar.
 Looks like the highest "financial risk" you took is behind you; I hope they have the connectors!

Here's a link for those who want so spend even more on OEM Nav enhancements!

Okay i got the low down from SCOTT, here is what he has on the VSS wire....

Pin "A4" from the instrument cluster harness to Pin "E" in the C2 harness on the back of the HU.

I found my AUX cable today and im going to get that wired up as well.

The NAV antenna is holding me up now.....i cant find anyone who has it, and they are telling me 5 days minimum for delivery.  I HATE DEALERS!  I had to stop at a GMC dealer to get a VIN from a Denali that had this as OEM equipment before they would even try to order it.  Try explaining to a dealer that your installing a NAV radio (that they say you cant get) into a Vehicle that didnt come with that option (that they say wont work) and tell them you need an antenna to plug into it that they say you cant get without a VIN (that your vehicle doesnt have because it didnt come with that option).  My head was spinning and if i had my gun with me i would probably be in jail now.  Long story short, i had to postpone programming until i can get this antenna.  Now that i gave them a VIN that has that option in it, they say it might be 5 days or more until i can get it.  Unless anyone here knows how i can get one, or has one to sell......it may be until next week till i wrap this thing up completely.  I will keep you all on the up and up as things progress

GM parts direct - ship next day air (or overnight, if you want to pay for it)!
Get the order in quick!

Typical, but I wouldn't be surprised that it isn't a stock item at a dealer..

That "You can't do that" is a common response; I have fun with it now.

Edit: I believe it's a "common" connection in the HU; available at either connector. The HU print shows one way, the cluster print (showing the HU connection) shows another....

[gable74]

I tried to order from GM-parts-direct, but i kept getting an "out of stock" error on the reply E-mail.  So it seems they couldnt get it either.  Looks like i will have to wait unless someone has some inside info for me.. .

im in the process of wiring up my 6 disk changer and i noticed there is a pin for "Instrument panel lamps dimming", #8 on the 9 pin Slave harness.  I know it hooks to pin "B4" of the C1 connector on the HU (according to DOC #1248651), but i dont know where to pick it up from on the truck.  Do you know which pin on the instrument cluster harness is for the dimmer?  I PMed Scott so hopefully he will know if nobody else does.

[gable74]

One other thing that i know will help those who are going to hook up the 6 disk changer.....

Buy the 9 pin to 9 pin slave harness part #15312903....its $22.  You only need one end that plugs into the slave device because the other end needs to be pinned out and plugged into the correct locations on the C2 12 pin harness on the back of the HU.  Dont "CUT" the other end off, just remove the pins with a paper clip and they push right into the 12 way harness, all you have to do is put them in the correct locations.  They are the same type of pins!  This makes it very easy to hook up.  I am going to make up a DOC showing the 9 pin to 12 pin harness and what goes where, when i finish up and verify that it all works 100%.

You don't need to deal with it; the HU will adjust by it's settings, the Day/night sensor and by your dimmer wheel without having to add/change any wires.

Good call on the changer harness; the easy way out!

Call around some scrap yards; maybe they have one they'll sell W/O the HU.

Didn't the dealer check around for stock at other dealers in the area?

BTW, do you post your images on a web page and link to them or post them here; I can't find the command to upload an image from a local computer!! `Never did one!

[gable74]

i tried EVERYWHERE! no one had any at all.  I will just have to bite the bullet and wait a few days.  Thanks for the info on the dimmer wire.  I kinda thought i didnt need it, but i wanted to be sure.

I am part of a few other forums, so i just post pics on those forums and use thier HTML addy to link the pics to.

[sperry]

Oh well, at least you didn't buy it before you didn't know that it worked... Enough of a risk already.

I reply / check on the "recent posts". That covers the open forums as a whole.
I just post new subjects in the specific one.

I never received an answer from the "knowledgable"; except just once, but I don't have that resource.

Hey Steve

the schematic is wrong. B4 Is the dimmer wire.
Scott

[gable74]

okie dokie, just an update.  Got my cable made up and it worked out perfectly, the pins just slid right in where i needed them to into the 12 way "C2" HU harness.  Best of all the changer worked perfectly.  Looks like there is NO programming needed.  Appearently it is self detecting, cause i hooked it all up, and hit the "DISK" button, and the "CDX" symbol popped up and started playing the disk in the changer.  Damn this is sweet, just a week ago i was thinking i had the wrong AMP and a bad NAV HU.  Cant thank Steve and Scott enough for the help.  All i need to do now is wait till the antenna comes in and get it programmed.

[AvaZ71]

CONGRATS ;

Can you please send me any schematic you have for the 6disc,I am in the process of getting all the components just about have everything.

Question ...do you have XM,also I need part number for XM factory antenna,if you have it.

Thanks...Richie...

[gable74]

I dont have XM, but if you send me your E-mail i will send you what i have for the 6 disk changer setup.

Scott

Now, that's weird! The HU connection diagram says that too; the cluster print has it as ckt 817 (VSS)!  Mine works though. Hmmmm.

 I thought it was getting dimming data from the class II bus, until I saw that! I'm sure that the VSS was on the larger connector! Isn't it the same as the old HU, except there was no conneted wire for the VSS?

 I really have to be careful poking things into empty holes!

  Really good to hear that Jimmie!
Scott mentioned VSS wiring print conficts; but mine works! For now, follow up on what he did.
 I was covering it with my contracted installer and only worked with him briefly and saw it poked there, then got back out of his way. I'd have to pull it to see but Scott has more of a first-hand at it.

 We know that the amp is "flashed" to a configuration now, since your's worked from used eq. There's a good chance that the speaker wiring is the same but I'd compare the Hummer print and your's to be sure.

Kinda neat to be unique eh! "Naverado" maybe?

[gable74]

LOL, yeah...but i was thinking more along the lines of Escarado!  

Sounds like to me the BCM is set up from the get go, to accept what ever radio configuration is fed to it.  Cause my BCM was a base level UC6 setup and it responded just fine when the new equipment was installed.  Any idea what the speaker set up is in the Hummer?  To be honest, im not 100% sure what my setup is.  Im pretty sure its 6 speakers....two in the front pillars, two in the door panels, and two in the back.  Either way it sure does sound a hell of a lot better than the old one.

[sperry]

  Maybe go to a hummer lot or ask the parts guy that helped you....

  That's weird how much better sound quality you get; an added benefit...
 
 Now, get an XM module; you'll love it, I'm sure!

[pbuilder]

Steve
yours must be in the right connector or it wouldn't work.  I trust the conector pinout over the schematic.

the HUs get programed to the BCM except this one doesn't. the amd gets program for the cabin size and speekers . I should check to see if the rear tweeddlers work.  I got a diffrent amp #15054675 and had it programed the other day and it works. need to have them turn the mic on for they didnt check it when they did it.
good deal on the 6 disk Jimmie and the nav. Did you get the nav disk with it.

[pbuilder]

Just check the H2 and it has the rear tweeddlers installed so it is like the Denali.

[sperry]

Steve

 Agreed: The simple fact is the open spot on the connector.
The dimmer connection is already wired to the other.

[gable74]

I dont have any dimmer connections made at all.  I thought i didnt need them. And i made my VSS wire from Pin "A4" of the instrument cluster harness, to Pin "E" of the C2 HU harness like Scott said.  I hope thats right.....i will see soon enough.

Yes i got the NAV disk, all im waiting on now is the NAV antenna and i can get it programmed.  Its all working perfectly.

So if the hummer is set up like the Denali....i will definately need my AMP tweeked for the cabin size.

Almost done now, i can see the light at the end of the tunnel!
