I finally got around to installing a new head unit in my camaro. a friend and i were doing it and after we put it in we went to reinstall the faceplate that goes around the AC\heater\head unit and realized that we lost one of the things that the wires plug in to. its not the one that turns on the fog lights and looking at the piece it looks like whatever it plugs into doesnt even do anything. any idea what it is and how vital it is?

 

Is it the one next to the fog light switch? On my car, thats for ASR, which Im guessing is traction control.

 

Are you looking for the HVAC panel connection for the lights in the panel?
