When my 1986 Firebird came off the assembly line, there were certain options you could get and i didnt get them. I now want to install these options..I installed the harness and switches for the rear defogger and rear hatch release and sub-woofer. Does the car come with the amp for the sub-woofer?..Does the rear defogger relay timer there or not?..and where in the heck is the relay located for the rear hatch release lol?.Gawd, I AM GOING NUTS!!!!!!!!HELPPPPPPPPPPPP!!!!!!!!!!:hail:
