66 gto electrical problem
 

helping a friend put together a 66 disassembled 12yrs. ago . No wire harness so he purchased new H&M i think. Of course wires are not labeled and no old harness to go by. when ignition switch is in on position tail and backup lites come on also cigarette lighter got hot and melted!! Any suggetions much appreciated . Bad ground , wires not hooked up correct ? Thanks in advance!!!

Hi, did you try calling M&H they may be able to help.

Get a wiring diagram. The M&H harness is an exact copy of original, so all the wire colours will be correct.
