ON 1-18-11 we installed a set of emergency strobes and LED's on a 2009 Charger for a Vol. Fireman. The groung side of the battery was removed briefly and now there are no heat controls and the airbag light is on. None of the factory wiring was altered in anyway. The heat controls were unplugged from the dash ***** so the the switches could be installed. They were all labeled and returned as they were found. Anyone have any ideas?
