So I am still trying to make it so I can use the fog light dash button for my cobalt. Over Xmas break I bought a harness from eBay recommended from a guy on this forum. The headlight harness fits in with everything, except the three slot connectors under the radiator. I had to improvise and now my car needs a new headlight harness. The guy said the ss harness number is 15854009 Long Story short I was wondering if my default 06 LT model can fit in a OEM 06 ss headlight harness with fog lights? Your responses and actions are Greatly appreciated.
