ok so ive been trying to swap my doors over from manual to power my car is a 95 mustang gt. well now that i pieced everything back together in the interior the last thing i was going to do was install the door harnesses and plug them into the car harness. well the door harnesses have a grey and a black connector . my dash harness has a black and a 6 pin brown connector and the driver side of my car harness has a grey and a black plug but have different guide shapes that will not allow them to plug in (they are close to the same but they are different) can someone please help me figure this out because i do not want to butcher any wires but i need to get my car on the road again thanks alot and happy easter !
