Hi--Never been here before but have a non functioning trailer light plug I need to repair or replace. Plug is OEM and I want to eather update or repair because I have no power to the left tail light/brake. Does anyone have a schematic of this harness? I have power to plug behind right rear fender well but not at trailer plug. Any help here? Cant find a wiring diagram anywhere. Thanks

 

Is it a 7 pin plug?

 

Thanks--It's a 7 pin.
