It would be easier to just get the 87-93 center wire harness that runs between the new doors, if your new doors have all the wiring intact. The center harness hooks to the main harness with only two wires, one hot all the time for the locks, and one hot with the key on for the windows. They are both grounded through the drivers door. That way you will have all factory wiring and only two splicing of wires to do. The wires run across the top of the dash in the 87-93 cars, so they are a bit of a pain to pull, but easy if the dash is loose or removed.
I have the door wiring diagram I think at work, I can send to you if you want.
Good luck!
