sounds like somthing is differnt on the pontiac then the hhr. I do know that the air bag code will not clear if the problem is still there. if you put your old harness back in I'll bet you will be able to clear the air bag code. You need to find wirring diagrams for both cars and compare them. let us know what you find.

Any trouble shooting advice for me: I bought harness 15234343 have the audio switch ending in 51 (and another from a Solstice ending in 58) and the cruise switch ending in 50 which should be correct pieces for the G5. Car has MP3 player CD radio that had the DIC buttons on left and smooth piece on right (where the stereo buttons are). it is a November 2006 built 2007 model year Pontiac G5 with all power options (Like a Cobalt/HHR LT).
The new harness when plugged in has the wires running opposite where the radio would be on the left and cruise on the right. It will pull the other way and do fine which is not really my issue.
The harness has 3 plugs. 1 for the radio, 1 for the cruise, and 1 2 wire plug for? The new harness does not have a "red" plug to get the horn reconnected either.
I did not do anything with the clock spring or any of that, plugged it all in, went to turn on the car and the Service airbag light is on. Radio controls don't work, and I know I have to get the BCM redone to have the cruise function so I can't say if it will work or not. It appears that the buttons light up fine. Not sure what I am doing wrong, or if the steering wheel buttons will not work now that the airbag light is on.
Let me know if there are any fixes. I used my OBD II to try and reset the airbag light, but it did not work so I guess I need a Modis or Tech II for the fix. Do I need a new clock spring or anything to make the rest work, or rewire the unit to get it to run at all?

I have not done the mod, but have read the thread. Why would you need to have the BCM flashed for the cruise to work? As I read the thread, you DO need to match up the color codes of the wires because some harnesses are wired different, Just make sure the colors are the same on both sides of the connectors.
I just unplugged the battery for about 2 hours and now the airbag issue is not on. It was weird that the car gets power to the switches, they light up with the lights on, they just have no function.

My car did not have cruise standard. So I would have to get the BCM to turn it on. I don't know where the 3rd set of wires plugs into since I don't have anything to plug into the horn button "Red" plug. 2 are flat mini connectors, the red horn button is round. The Harness had 3 mini connectors. '07 wheels should be about the same across the board.

When I got my leather pontiac wheel, it had a different horn connector, a red round one like you describe. It doesnt match up with the chevy horn connector. The button bezels were also slightly different in the mounting screw locations. I ended up just swapping the whole wheel as the individual parts would not work.
Ill see if I can dig up some pics of the different wheel setups.

Here we go, found em.
This is the chevy wheel, not sure if you can make it out, but I think the horn connector is a black square plug on the far right.
Here is the pontiac wheel I used, you can see the horn plate is different.
Here is the horn plug on the pontiac, it will not plug directly into the chevy wiring harness, which Im guessing is the one you have.

Prod, you are right on! I know a few guys had done this mod on thier Cobalt which is the same wheel as the HHR I assume (Chevy to Chevy cross compatible) I tried to find a few G5 guys. I did, and they were able to do the swap as well. Acted like I was crazy when I mentioned the red plug. I guess I need to find the part number to an '07 G5 with thos options. The buttons are the same for me along with the same part numbers across the board, just the harness needs figured out now. Thanks for the post!
