Adding Steering Wheel Controls To My Truck...

G80 · September 13, 2008

I have a 2006 Silverado Crew Cab. It didn't come with steering wheel controls from factory, so I have decided to put them in myself. I have a new steering wheel and clock spring. My question is, does the entire wiring harness have to be replaced as well, or just the clock spring? My new spring has a large harness attached to it and I'm not sure if it can be detached. I seemingly cannot find a connection to seperate them. Anyone have some tips?

The correct SIR coil or clock spring is part # 26101829. This is the clock spring and wireing harness as a unit. They do not come apart. You un-hook the old harness and remove the clock spring and install the new one. You will have one extra plug that is not used unless you have quadrasteer, which you dont as they did not offer that in 06.

The Dealer will have to program the DIC as well as add the option of redundant radio controls. Not as easy as one might think. They have to get the proper code from the tech line. Some dealers will not know this as they have very little calls for this. Good luck.

There have been many threads on this, on this forum as well as others.

I have read a lot of the other threads on this subject. I just wasn't quite sure if the harness had to be replaced as well. From what I under stand GM # 26101829 has been replaced with GM # 26090779.

It could have been. When I bought the clock spring for my 05 it was 26101829 per MS3DALE. Actually the new harness has the connections for the Dic and radio controls, while your stock one does not. Thats why you replace it.

Awesome! Thanks for the info. Hopefully I will be able to get the parts installed in the next couple of days. I have already spoken to the GM dealship and they said that they have done a quite a few of these upgrades, so the programming should go smooth (I hope)!

GMpartsdirest does not show 2690779 as being a good part #. The catalog does show part # 26101829 as being the correct clock spring for a 2006 with accessory controls.

On another thread I read that 26101829 had been replaced with 26090779. I sure hope that is correct, because that is the part I have!! The box from GM said 26101829 on it but the part inside said 26090779.

If it had 26101829 on the box you have the right one.

Have a good one,

Does anyone know how to take the 'Tilt Steering Knob' off so that the top and bottom portions of the steering colomn can be removed? I tried this afternoon to install the harness, but I was not able to take the bottom colomn cover off because of the tilt steering knob.

Any ideas?

Ok, my brother-in-law and I installed the wiring harness in about 2.5 hours! BUT, we have two plugs left over. One is a 8 wire plug which we know is for Quadrasteer, but we also have a 2 wire plug with a neon green end left over. Does anyone know what this is for or where it goes?

I think that is an extra too. I added the steering wheel buttons to my 05 crew cab a couple years ago. The hardest part was trying to get the dealership to reprogram my truck. Just be persistant. It is worth it.

I know this is an old post on steering wheel controls, but I need some SERIOUS help.

I followed directions I found on this forum to add controls to my 06 Silverado LS Crew Cab. Got a steering wheel, got the clockspring/harness # 26101829, and uninstalled the old stuff, put in the new stuff. I had only 1 plug unused, a neon green one I read I didn't need. Took the truck to the dealer to flash the VCI numbers they got from GM. It fried my BCU and instrument cluster. Now I'm looking at $1,100 to replace those parts.

What the F did I do wrong?

All the plugs on the harness can only go in their own place, so I know i didn't cross anything.

Is it possible they sent me the wrong wiring harness?

Is it possible the dealership screwed up uploading the codes to my truck?

Should I put the old harness back in and pay these guys?

PLEASE HELP

Since the truck was under THEIR care when it blew up it should be their responsibility...I might want to consult an attroney to cover your ass in case you have to take em to court...I know they would be getting a facefull of me and a mountain of papers beginning with "lawsuit" and ending with "you're going out of business".

FALC0NDRIVER · May 14, 2009

I'm married to an attorney, so that part is cheap. But I don't know. They did do what I told them to...allegedly. Right now I want to figure out what's going to get my truck running, and If I did anything to cause the problem, since I put the harness on myself. I'm sick about the whole deal, but I'm definitely NOT paying 1100 bucks to get my truck back without the controls working.

Really, what I need to know in order to have a case, is what conditions would have to be met for flashing a truck's computer to fry a bcm and an instrument cluster.

Anyone out there with computer flashing experience? I don't know anything about it.

Ranger · May 14, 2009

It has to be something in a wire that was not active before the flash, that's for sure...I did the steering wheel upgrade myself but my truck is prewired for it and it worked with no BCM updates...So it's possible you got a defective harness that shorted out and took the BCM with it...

Easiest thing to do is find a junker truck around the same year and pull the BCM off that, but that'd be tricky as there are a lot of different options that a BCM may or may not have programmed.
