Here is an install of steering wheel audio controls I did on my 2002 Sierra. It requires very minimal parts surprisingly. I have also installed these controls in a 95 silverado as well. - If you are installing these into an OBS truck please see the note below!

- You can install these controls in any 95-98 OBS truck. It requires the same parts with the exception that 95-97 needs to swap to the smaller style steering wheel & airbag. The only other difference when installing these in an OBS is you will have to change the airbag plug at the end of the SIR coil to match the one in your truck.

---------------------------------

Parts:
Denali/Escalade/Jimmy Steering Wheel - $65 shipped on eBay (you can buy the buttons and steering wheel trim from GM separately)
Denali SIR Clockspring Part # 26087300 - $85 shipped on eBay
Plastic paint (for trim) - $5
Misc Wire
PAC adapter (if you have an aftermarket stereo)

Tools:
Steering Wheel puller
Small flat screwdriver
Torx bits
The usual wiring "stuff"

Start by disconnecting your battery AND pulling the airbag fuse un the door jamb. THIS IS IMPORTANT. Let the truck sit for 15+ mins to allow for the electrical system to discharge. You don't want your airbag to go off in your face!


Start by first removing the dash bezel and lower dash panel. Under the lower dash panel also remove the metal shield with a 10MM socket. You'll need these out of the way part way into the project (found that out the hard way)

Now, removing the airbag. There are two small openings in the back, use a small screwdriver to release the clips holding it in. You'll figure it out after awhile.

Once the bag is released, unclip the electrical connector and carefully set the bag aside. Un-hook your horn wire (red) by turning counter clockwise. Then take the steering wheel puller and remove the wheel.
P6060083.jpg



Now your wheel is gone and you have this left.
P6060084.jpg



Now take the cover off the column by simply pulling it apart (I think older models had torx screws). You’ll also have to unclip the tilt lever (I think I used a small screwdriver on this too). No you are going to take the old SIR coil out of the column (the black thing with the airbag wire) and unhook it under the dash. You’ll have to cut some zip-ties and such. Take the new SIR coil and route the new wires and plug it all in. Route the new 4 wire plug for the audio controls where you can easily work on it later. Now, If you have a new SIR coil, follow the GM instructions that came with it and install it on the column. If you have a used coil, be sure it is centered on the column and you can see the orange thing in the window indicating it''s centered. If you don’t install it correctly it will become damaged and your air bag will not function, along with your horn and new radio controls. <THESE INSTRUCTIONS REGARDING CENTERING YOUR NEW/USED SIR COIL ARE VERY IMPORTANT. Be sure you center the SIR coil or damage will occur!
P6060086.jpg



Now move on to your steering wheel. If you bought a complete Denali/Escalade/Jimmy wheel and want to keep your factory wheel like I did (mines factory yellow, plus the Denali one I bought was very light grey) You will have to remove the controls and trim cover from the back, the re-install on your existing wheel. These all take torx bits. The back trim piece will also need painted if it doesn't match your interior color.
P6060085.jpg



Put the trim back on the column, and then install the steering wheel. Install is reverse of removal. Be sure you plug your airbag back in, and it just pushes back onto the wheel.
P6060088.jpg

P1010037-1.jpg



At this point you can re-connect your battery and put your airbag fuse back. Before going any further test for proper horn and airbag functioning. I suggest standing out of the truck the first time you start it. You can also (while still standing outside) cycle the wheels back and forth to double check that you installed and centered your SIR coil correctly.


If the airbag light is off and it didn't deploy, you’re ready to hook the controls up!


Wiring Info:

Black - Ground
Grey - Dash light dimmer +12v
Green - Keyed power
Yellow - Data wire

1. Cut the plug from the SIR coil and connect 4 wires to it, long enough to run to your stereo. I used OEM colors for simplicity.

2. Splice your ground, power and lights into your radio harness wiring however you choose. The Yellow signal wire goes to a pin in the radio plug that is empty. I shoved it in the socket and taped it in. It was on the bottom left of the connector next to the left most wire. (I’m going to get the pin number later).


Test out your new controls!!! If everything is wired correctly, the controls will do what they say on them (consequently, if they aren't they will do other things, such as not work or change channels with the mute switch). Be sure to check them at night to see if the backlighting works as well!!!

Re: 99-02 Steering Wheel Audio Control Install

i assume you need a stock deck for this? no wiring to aftermarket
PAC makes a converter box to make the controls work with the aftermarket deck, but must be a remote control capable deck.

Re: 99-02 Steering Wheel Audio Control Install

Correct. I'm using my stock deck as of now, and you can get aftermarket PAC adapters, as long as the deck has a IR or wired remote.

If you read the first coupe of sentances, you'd catch that I have also installed a set in a 95 Silverado :biggrin:

I do but they are not uploaded to the internet. The procedure is extremely similar, the only differences are in the way the dash and column shroud comes apart, otherwise the internals are almost identical.

If you'd still like to see the photos I can upload them at a later time (although I'm pretty bust ATM)

Does anyone know where to get the 01-02 Denali/ Escalade Clockspring(p/n 26087300) for less than $150? The original post says it was purchased on ebay for $85 shipped. I've had no luck finding any listing on ebay for this clockspring. Obviously, gmpartsdirect.com & partszoneonline.com can offer a better price than the dealership. Just wondering if there is better source to find this item. Thanks in advance.

01 & 02 only. Your best bet is to find a complete steering wheel, and reuse the parts. Ebay has them pretty often. I chose to order the parts seperately, and found out that the shroud that screws to the back of the steering wheel has been discontinued. Luckily, I found the last one in the country, and it should arrive in the next few days. I believe that there is mention of a PAC adapter in this thread which can be used for aftermarket head units. Most of your stereo retailers can order one for you. Just tell them you have a 02 Escalade.

Exactily what he said, the audio controls came in 01-02 Denali and 02 Escalades.

They were also available in some S-10 series Blazer/Jimmys, but I don't know what years they range from.

As for a pac adapter, crutchfield has them, or any other stereo shop.

Really sorry to necro this old thread but i had to comment on how helpful it was in my own install of a set of controls from an 02 Blazer. although the backlight on mine does not work everything else seemed to be spot on. I did notice that it lists the wiring colors as green for 12V switched and yellow for signal, however those two are backwards.

I know this an old thread, but it's the only one that comes up for that steering wheel I have. I have a 2001 Silverado with a pioneer nex 4100, the controls come off a 2002 escalade, I'm using the ASWC-1 Axxess Steering Wheel Control Interface. I would like to know what wire color is what, since there is two different wire breakdown described in this thread. I've tried both ways with each one of the 7 wires coming from the axxess control box and and get the same response of blinking lights. I've called the tech support number for axxess they say they can't help me. I've been working on this all day, I've got my dash tore apart and I'm not getting anywhere. Any help is greatly appreciated, thanks in advance.
