Steering Wheel Radio Controls Wiring Diagram

irocg88 · April 2, 2010

Well i bought a few things, I bought the buttons, and the metal connectors i used to plug into the buttons. These connectors were pretty easy to find since all i needed was something that fit snugly onto the prongs inside the buttons. The connector that i needed for the plug that goes into the clockswitch was a different story.

I had a very patient parts counter person who looked for about 45 minutes for this very hard to find connector. This is the wire that is not included in our factory harness, so it must be added. It is the one that goes inside this plug (highlighted in red) The part number on this little connector was 15305174. I don't know if that is a GM Part number or a delphi part number, but hopefully it gets you started in the right direction.

For the shroud, i took a piece of paper and traced the cutout for the cruise control side and then traced it onto the other side of the shroud. I'll see if I can get a picture tomorrow. The cutout isn't perfect by any means, but you cant really see it because of its location.

Here are the connectors I bought from the dealer. Soldered them onto the wire and then added some heat shrink tubing afterward.

After I added the heat shrink tubing, i pushed each wire I made onto the prongs inside the buttons. After I got them all pushed in all the way, i took some ultra black silicone and filled the rest of the cavity where the factory gm connector would go. I did this to lock the wires in place so that they wouldn't vibrate out or get pulled out accidentally.

Then I spliced the three wires i needed into the factory harness. Re-wrapped the harness with electrical tape and reassembled.

Edit: I belive the part number I listed above is a delphi part number

What three wires did you splice into? I am trying to do the same thing on my impala, which has the same stereo and controls.

You can splice into the remaining wires anywhere in the wire as long as you get the correct color wire. The oem connector to the radio controls (which we do not have) is not labeled, but looking at it from the top/front of the steering wheel the wire colors are: Black, Brown, Pink w/Black stripe, and Light Green. I simply used a utility knife and stripped a little bit of insulation off of the wire wherever it was convenient. The soldered the new wire to this spot and taped them up good.

Take the wire you have placed in the top most position in the switch and splice it into the black wire in the existing harness. The wire you put in the second place from the top should be spliced into the brown wire in the existing harness. Third wire will be spliced into the pink w/black stripe wire in the existing harness. And the Fourth (or furthest to the bottom) wire will be the new wire that goes into the "c" position.

The reason we have 3 common wires in the rest of the steering wheel are because 2 of the common wires are used for backlighting in the radio control switch, and one supplies either a common power or ground to both the cruise and the radio switches.

Hope this helps,

Where did you buy the radio buttons?

I snagged my buttons off of ebay, but you can order them from gmpartsdirect or from your local dealer.

Nice job man I trying to the same for my truck, I drive and 2007 Silverado, I bought new but I got tired of manual lock and manual windows and mirrors, so I went to a junk yard and took a part a lt Silverado and bought the door panels with the electric windows and locks electric mirrors, the center console, the speedometer, and all the silver trims for the truck.

I made all of the above work just the electric looks couldn't.

And the steering wheel that I bought was the volume controls, and I also took from the truck in the junk yard the clock spring, and I been reading this log, I decided it's time to get mi volume controls working,

Thanks to you

But I just have a couple of doubts, the first picture in this post that you added is the connector of the clock spring right or is it from the radio?

Please man, guides me a little bit so I won't mess up my truck.

I would appreciate it.

Thank

The pictures I have posted are all from in behind the air bag. Which would be where the harness plugs into the clock spring. I never messed with removing the radio at all.

Have to work on sizing images, but here is the black plug. If you already have cruise then you can see the wires going to that plug.

Is this the plug from the back of the radio controls?

danimalheim · November 22, 2011

Well got all the wiring done but the audio control lights stay on and the cruise control lights are off. I pulled my ignition key out and lights stayed on.

dlewis1111 · November 22, 2011

Not sure how much money and time you have spent on this, but a new steering wheel with all the controls and associated harness is like 95 bucks new from the dealer and takes maybe 5 minutes to change out. If you dont have factory cruise you can change the clock spring out to one made for cruise and then add the new wheel to gain the radio controls. Cruise must be "turned on" in the bcm by a dealer willing to do so.

I have a 06' Silverado with Bose, Onstar, Xm, steering wheel audio controls. I replaced OEM deck with new D-Din and is wheel control ready.

Someone please tell me which wires running out of the stock radio harness are for the steering audio controls.

I am wondering the same as well

Roger S. Renfro · February 12, 2021

Does anybody know which wires from radio harness goes to the steering wheel controls? I'm trying to hookup a pioneer touchscreen in my 2008 Silverado and I have the after market interface but I have splice into the steering wheel controls to get them to work w/ my pioneer radio and have no idea what color those wires are. Help would be much appreciated ,pictures would be fantastic too. Thanks a bunch in advance.
