Need to pull the door panel off and see if the harness is in there. If the car has power locks then the harness may have the plug for the window motor. If not,, when yiu get the doors get the harness that also, it should plug into the body harness witout any problems..
I suspose you would need different regulator assemblies and the wiring. I am thinking of swapping power to manual because I am tired of f'in with these motors.
I put the power windows and locks in my car when I got some great GT power door panels. If you have power locks, the center harness that runs from door to door may be the same, although I'm not positive. The door harnesses are different, though. You will need: power doors or at least the power window regulators and motors, the door wiring harnesses, the power door panels, power armrests and all the switches. If you don't have locks, I would get aftermarket lock actuators since they will work great and are very inexpensive for new parts. Easier to install also IMO. I have a link to an easy installation instruction page) Plus you need the harness that runs from door to door if your car does not have power locks, and the rubber door boots for the wires and a power window circuit breaker for the fuse box. Hooking it up is easy, the under dash harness plug into the main harness under the dash right by the drivers side kick panel, a two wire connector with a pink wire and another color wire.
If you have any questions about it, or need wiring diagram info, let me know!
