Yes, I did a cross-ref chart in MS-Word. It messes up in other WP's so `hope you have it!

BTW, to the club!

You will need to unzip this, but click on the link to D/L it.

Edit: Cleaned up the link... Replaced old file with updates that reflect changes to the RSA  wiring, instead of just the amp.

Hey all,
newbie to the forum, thanks in advance for the info.
I have an 03 sub without y91 package.
I purchased the following:
hu p/n 15108241
xm tuner and antenna module p/n 22692861
gps antenna p/n 15135178

I think all of this will just work with installing, and then taking to chevy to remove theftlock.
What I (believe) am missing is the wiring harness that goes between the nav unit and the xm tuner. Does anyone have a p/n for this, and input into what I am going to have setup (if it will work or do I need anything else).

Thanks again!!

[sperry]

That cable was integrated into the wiring if the option was OEM-ordered XM.

You may want to try JP Customs and see if they have the retrofit cable. It's part of the retrofit OEM kits.

I don't have my more "complete" list of equipment here at work.. The # sounds familiar.

[92coop]

I talked to jpcustoms and they dont sell the cable out of their $399 kit by itself.
I also decided to switch from the INR unit to a 2005 TNR unit and since I have a soundgate piogm1 for xm currently I called them to find out if it will work with a new tnr unit, they said no. So I will have to switch to the sirius kngm1 which does work with the tnr. That kinds sucks cause I like xm talk shows. I think I might fm modulate xm and digital connect sirius and try both.
Any suggestions? YOU DA MAN SPERRY (the guy knows it all!!!)

[sperry]

There's a member thad did make up a cable, but I keep forgetting who!

I think it's one of the NorCal group....

It's a 16-pin connector but I didn't see info on it.. I'll take another look.
The other end is easy.

Is it a single antenna unit (10333560)? You'll need to match the antenna. You can with a SkyFi antenna if you don't have a factory one. Just specify single or dual.

[sperry]

Here's the connector "info" as what they provide... (I always get messed up trying to find this, they call it by "Digital Radio Receiver" instead of XM.)

And I found this doc in my files..



Connector Part Information
   
The Micro64 XM connector is GM part number 15394150.

The pins with leads attached can be bought in a kit that has 10 pins/leads, and a pin extractor from SPX Corporation, part number J-38125-64SPL for about $3.  See Techlink Archive PDF



Micro 64 Repairs

Electrical terminals continue to become smaller. The new Delphi Packard Micro 64 connector system is the next evolution in densely packed electrical connections. Bulletin 01-08-45-006 contains information about repairing circuits equipped with the new Micro 64terminal. It’s used in the Powertrain Control Module connectors on 2002 Chevrolet Cavalier, Pontiac Sunfire and Grand Am, and Oldsmobile Alero, as well as the new XM radio on 2002 Cadillac models.

You can obtain a Micro 64 terminal package, J-38125-64SPL, from Kent-Moore. It includes a terminal pick, ten pre-terminated leads, and ten wire splices, which can be installed using the existing crimper from your Terminal Repair kit.You can order refills for any terminal in the J-38125 Terminal Repair Kit from Kent-Moore. Additional storage bins, replacement tools and complete replacement trays are also available by calling 1.800.GMTOOLS.

Note: There is more than one supplier of .64 terminals, and each has its own characteristics. The new Cadillac CTS uses a Bosch engine controller and has Bosch .64 terminals.

HTH!!

Edit: fixed link.

[midwest kid]

Sperry, can you post the 24 & 12 pin pinout for actual connectors that plug into the Nav Unit? Are they same as if there was a normal GM CD Player in the dash? Oh yeah, anyone have a part number for that 12 Pin connector?   Thanks again.

[flyingdutchman]

  Please correct me if I am wrong.I will be attemping to install a Touch Screen Nav into my 2004 ESV  UQ7 with Y91.  On radio connector C2  I should look  at pin E to see if  I have a DK GRN/WHT wire which would be the VSS signal to help smooth out the display. If not I need to install a pin into E  and tap into the IPC A4 pin DK GRN/WHT  to pick up the VSS. From what I read (and it's alot) is this  correct? Also would somebody know the part # for the pins ? Thanks in advance

[sperry]

You're right with the info you gathered so far. It's highly likely the ESV has that connection. You should ONLY have to add the GPS antenna. But it's good to check for the VSS connection anyway. Hopefully your harness isn't tight. If so, you may as well remove the dash top to get to it. You need to access the GPS antenna mounting anyway. (PM me if you didn't find that location drawing).

If you had the older J/S nav prior, all you need is to R&R the head units if the TNR is brand new. But remember to eject the old unit's DVD first! Unless you obtained an updated one of course...

If you had no nav unit prior, you can just "Ohm" it out to see if it's actually connected to the VSS.

[sperry]

I posted it somewhere here on the board. May have been my door chime mute post.

These numbers are older ones:
Connector terminals:  GM  #12020757  for 20-18 GA
                                   GM  #12020758  for larger wire
I believe the smaller wire number crosses to a bag of ten now. The other number no longer shows. The bag is under $10 and most dealers can get it usually in a couple of days if they don't already have them.

HTH!

Yes, but it's better if I format the clip for posting first. Remind me later if you don't see them posted soon.

The aux CDX (audio) doesn't connect there directly (OEM). It connects to SP 250 splice pack connector that's atop the glove box! Electrically, you can however, connect it to the 12-pin.

[92coop]

sperry, in reply to  your post : "Here's the connector "info" as what they provide... (I always get messed up trying to find this, they call it by "Digital Radio Receiver" instead of XM.)

And I found this doc in my files.."

So I am gathering that you recommend to buy the gm terminal, and the kit from spx and splice it myself.
I have a couple of questions regarding this project.
1) I am not sure where the xm unit goes in my non-oem xm suburban z71. do you have a drawing or an article that helps with this. I am assuming that there is currently no wiring harness at the location where the oem-xm unit is supposed to be. I want to put it in the original location since the xm unit I bought has the original antena and by the length of the antenna cable it looks like the xm unit needs to be mounted somewhere in the roof/overhead.
2) after question 1 is answered and the answer is that definitely I have no hidden harness that will just plug into the xm unit, should I just buy wire and run it (neatly) where it is supposed to go (to the unit) or will the kit from spx bring the wire needed..etc.
3) I have called soundgate who make the interfaces and they advised that the xm unit will not work with the tnr at all because it is coded to the original vehicle (which they have tested). I dont think this is true and I think my project will work but I want those who really know to advise.

[sperry]

1)     I'll locate it and post it. You need a bracket that it clips to and holds the XM box. It mounts behind the Glove box.
Look at the chart, that's the connector block P/N from GM. The terminal kit is as you found. You need to make the harness up so it fits to the oem connection points. That will be the hardest, since you will be gathering & reading what info you collected while your `burb dash is in pieces. Measure the antenna placement from another similar truck. It's two holes.

2) I hadn't ordered the SPX kit - mine was an OEM unit. Another member did but I just can't remember who that was.
From what I see, the wires that they had pre-attached to the tremonal pins are too short for your needs. Get a pack of 22 to 24 Gu wire near, or the same ins. color as the chart indicates for each wire, some heat shrink, solder, etc. Loom it and tape it up.

3) That's unexpected information from them. I too have trouble with that statment; it doesn't add up. Other's here have installed swapped out units. The only fact I hadn't confirmed is the necessity of the XM unit's original install VIN information; you may need that. These XM units work "flawlessly" with a TNR or INR; their statement is just plain wrong in that respect.
 
You may need this:

Digital Radio Receiver Setup

Important

The Digital Radio Receiver Setup option does not contain a submenu. Digital Radio Receiver Setup will configure the following systems:

    * DTCs
    * Class 2 radio messages

For the Digital Radio Receiver, complete the following procedure with the key in the ON position, use a scan tool in order to properly set up communication:

1. At the Main Menu screen, select Diagnostics.
2. At the Vehicle Identification screen, select the following options:
3. Model Year
4. Vehicle Line
5. At the System Selection Menu screen, select Body.
6. At the Vehicle Identification screen, select the following:
7. Platform Type
8. Body Type
9. At the Body screen, select Digital Radio Receiver.
10. Select Special Functions.
11. At the Special Functions screen, select DRR Setup.

XM Activation

      Important

      After replacement of an XM Radio receiver, call XM Radio to deactivate the receiver that has been removed from the vehicle and activate the new XM Radio receiver.

1. The vehicle must be parked in view of a satellite within 24 hours after an activation call.
2. Turn the radio on, tune to the XM channel 0, and record the Radio ID.
3. The Radio ID will be needed for activation of the new receiver. Call XM Radio at 1-800-556-3600 to deactivate the faulty receiver and activate the new receiver.
4. Park the vehicle outside in an area with an unobstructed view of the southern sky.
5. Leave the vehicle outside with the ignition switch in the ACC (accessory) position and the radio on for 30 minutes to activate XM service.
6. Once activated the radio will receive the remaining XM Radio channels.

Sperry thanks for the quick reply. The combo I have in the ESV now is U1S (in dash 6-disc) and the UB1 (AM/FM/CD/CASSETTE) I have picked up a TNR#10377531, GPS antenna and 3.0 Disc. I will be removing the dash top to install the antenna. I would like to pick your brain again in regards to the following:

1) The reason you need the VSS signal combined with the signal from the GPS antenna is to smooth out the moving postion shown on the screen and to have a up to date location of where you are.  If you do not have a VSS signal, your position would only be acquired from the GPS antenna, which would cause jerky movement on the screen and not have a updated location of where you are.

2) What do you mean by you can just "Ohm" it out to see if it's actually connected to the VSS?  What scale on the ohm meter? Black tip to ground, Red tip to PIN E? If I show resistence then I have the VSS circuit? What position if any does the ignition have to be in. Ex: ACC/ON/or ON engine running?

3) According to the shop manual, PIN E is not used. If on PIN E there is a different color wire and it doesn't "Ohm out" do I cut it or just tap into it?

4) Once everything is installed I can put ignition in ACC position, remove radio fuse, reinstall fuse, which would allow me to see if radio functions. If I try to start engine Theft-lock will appear.  

5) New part # 12089649 replaces  #12020757  for 20-18 GA
 

Thanks again for taking your time to "enlighten me"  I am hoping to install all this over the weekend and wanted to be prepared for what I might find once I open everything up. I have appointment with dealer on 12/30 to remove theft-lock.

[sperry]

`Shows here...



However that still doesn't mean it's there or not.

"Ohm it", Not check for voltages or shorts to ground. No power, in fact, disconnect the batt if you're poking around in there. You should only have to reset your clock... maybe other minor stuff, at all.

Put your ohmmeter to R X1, clip one end to the cluster A4 and the other to the HU connector 2 "E" (if the wire is physically there) And see if the connection exists (Maybe 1 or 2 Ohm's, if not less..) If the wire isn't physically there, of course then you just add it...

That terminal # I had but it was in the back of my truck. I thought I wrote the sub'd # down somewhere. Fortunately, they found it for you.

Edit: Missed an answer..

[92coop]

sperry,
thanks for all the great detail. i have one question before i start wiring: i have a picture of the gps antenna and where it is supposed to go, but i cannot tell from the picture where it goes. which is the front and back of the dash??
thanks for all your help.

[sperry]

The lower right is the front of the vehicle. Look closely around the middle, you'll see the drawing of the rear of the radio HU.

The arrow is pointing to the front of the vehicle.

Edit: Rephrased a statement to not sound so insulting!  

[nota4re]

Well, the GPS antenna finally arrived today and I installed the 7531 TNR in my '05 Denali this afternoon.  With the dash removed, I did find that GM has, in fact, now included the VSS wire in the connector going to the HU.  I have to find a dealer tomorrow with a Tech2 and a few minutes to get the VIN programmed.

[sperry]

Call it a "Theftlock clear".. Hopefully they have a ½Hr min. or less. If they want an hour labor, they're ripping you.

Good to hear the wire is there in the Denali. Now to see if it is in an Escalade ESV, which I would believe is present.

Let us know how it works out!...

[3782steveo]

Ok, I've been watching this topic for about a month now. I have a 2004 Silverado SS I'll be putting a 7287 TNR headunit in as soon as it gets here. How difficult is it to pull the dash top and install the GPS antenna? I believe I understand the vss wire from the dash cluster to the headunit, that doesn't look too difficult, just not too sure about yanking the dash top off.

Thanks,
Steve

[sperry]

 Sometimes the dash top is necessary just to remove the connectors from the rear of the head unit. Some pull the HVAC controls to access them, and that's that. But whether you can get it out easily or not, the dash top removal is mainly for the correct GPS antenna mounting (as you see drawn above) and second for connecting an optional OEM aux audio device (correctly) to SP250, which is above the glove box.

The VSS wire can be "fed" through the rear of the cluster cavity right side, and easily over to the radio C2. No top removal is necessary.

[3782steveo]

So, how difficult is it to remove the dash top?

[sperry]

OK, this may get tricky for you but I can post the document, but PKZip destroys the .gif's when it compresses or extracts them. So, I can't post a 7-zip compressed extension here, which utility apparently handles the gif's ok.

Solution (Actually a work-around) apparently works, but is a bit klutzy...

I place the 7Z archive in the zip archive. It apparently works.

You will need to find a file archive site; 7-Zip is usually available (shareware)

Use winzip or pkzip and extract the 7z file inside it to a temp directory.

Install 7-Zip you hopefully found it and run 7Zfm.exe for extracting both the .htm file and directory.

The .htm file should bring up your browser to view & print the dash removal instructions.

 Whew! Good luck. I'll try to post the document but one pic per post takes some doing..

[3782steveo]

Got it all unzipped, and un "7zipped" perfectly. Thanks so much. I can't tell you how much this helps.

Thanks again,
Steve
