Steering Wheel Radio Controls Wiring Diagram

I tried searching, but didn't find anything. Since a NNBS wiring harness isn't available, I wonder if the standard cruise control harness can be modified to accept the radio wiring. I looked at my harness, and it has 3 open slots in the plug to the SIR coil, so can it be as easy as picking up a pigtail and adding the wires to the other harness? Could any of you who have a harness handy check it out and let me know what wires go to the radio controls and where on the plug they go?

 

Thanks!

P.S. Maybe some pics of the connectors would be helpful

Damn, nobody has a harness out of the truck right now? I guess I will have to wait until I head back to my parent's house and pull apart my father's new truck to trace the wiring!

I have a used gray avalanche steering wheel with the controls that I'll look at when I get home.

The SIR coil connector has letter designators for each of the wires as follows:

 

A - Grey

B -

C - Light Green

D - Brown

E - Pink w/Black stripe

F -

G -

H - Dark Green w/White stripe

J - Tan

K - Black

 

The connector to the radio controls 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. Your Cruise control wires should be (not in order) Grey, Brown, Pink w/Blk, Dark Green w/Wht, and Black.

 

I don't know how the controls work with both sharing three common wires but it does????

Wow, I thought that they would go to the open slots and just have a wire or two shared...guess I was wrong! Thank you so much for checking this out for me! Looks like it should be fairly simple to tap into those wires and add the buttons without buying another wheel!

I just bought a steering wheel w/ audio controls. After I read this post I figured I would take some pics while I had the wheel apart cleaning it. Hope this helps along with Gil85's post. The 2 smaller plugs are for the switches, the Black w/ 4 wiresis for the audio controls and the gray is the cruise. Both are from the top of the plug.

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.

Hi all. I just purchased a 2009 Silverado 1500 LS and like to know if I can add steering wheel controls for radio and if possible for cruise control later.

Thanks

AHHHH!!! i used to make those steering columns...i worked at delphi in michigan...i cant escape that place! ha ha.

 

on a side note, you can modify them. i dont know the exact way to do so, but i know you can (having built them for 2.5 years...ya learn goods and bads about them). like the fact that half the columns are made by drunk people. :D

Joe, welcome to the board! As far as adding cruise and audio controls, you may be better off starting a new post about how to add them. The steering wheel change/ audio control addition is mainly for a truck that came with cruise control. To add the cruise, I imagine (but am not sure) that you would have to add a wiring harness to the column and a BCM programing/replacement. Once again, a new post would probably get the traffic you need to answer your question.

P.S. Thanks everyone for your help. I ended up getting a good deal on another steering wheel, so I didn't have to splice any wiring like I first thought I would have to.

Glad all worked out for ya! I just added the controls myself and love them. Had em on my 07 but my 09 didnt come with em! Didnt think i would miss them. I thought wrong :D

Thanks for the insight. It looks as if I won't be able to or at least at this time as GM will not allow the BCM to be reprogrammed to allow cruise to be turned on in vehicle that came without. DAMN, Never thought I'd miss it either. :D

Man that sucks! I mean really whats the big deal. Sounds like they just dont want to mess with it. I already had the cruise. Anytime I have taken my truck to the dealer to have something programmed they have never given me the line of Oh we cant do that or anything along those lines.

 

 

Well maby someone here has added cruise to one of these style trucks and can help you out!

I have a 2009 chevy silverado. The cruise control buttons are on the stearing wheel. I would like to add the radio contros on the stearing wheel. Do I need to add wires to the stearing wheel column or are they already in place. And any idea where I can buy the radio control buttons.

Thanks for your help

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.
