Got a 97 gtp 2 door that was wrecked and I went to the junkyard today and got a drivers door and when i went to put it on I noticed the wiring harness plug in is completely different than mine. Must be off a later model grand prix. The door i got has just one big plug and my old door has to one big and one small. What will I have to do to make this door work? woud it be best to just pull the doors apart and swap all the wiring? how hard will that be? Any other suggestions.
