Alright so i was lookin at the back of an 06 ss/sc the other day when i noticed that there are 2 stock harnesses that plug into the stock radio...the car has steering wheel controls and the pioneer 7spkr sound system, on mine (Base) it only has the one stock harness....the second on the ss/sc is considerably smaller i was just wondering wat it controls...

 

I don't know but I tell you it doesn't do much...lol Mine isn't hooked up anymore and I am not missing anything. The steering wheel controls are hooked up through the regular 25 pin (larger) harness....

 

So wtf is it for? anyone know?
