converting manual windows to power?

i was wondering if it is possible to bolt in a power window regulator in place of my busted manual one in my 90 rs without any fabrication besides wiring. if so where is the best place to get one? the junkyards where i live only have a few integras that you would be lucky to find one with a door on it and the dealers want a lot of money for a new one. thankx for the help

The things that you would need to convert to power windows include:

Window motors
Door panels
1 relay
Harness within the door
Main control unit on driver door
Power window assembly
Piece of the harness that goes to each door

What you need to do is:
Fill in the missing pins on your existing harness with wire from the peice of harness that goes to each door. It should be about 5 wires for the drivers door and 3 for the passenger. Swap all the motors, power window assembly, and door panels. Run the new wires under dash to the fusebox where you will tie into the relay with fuses.
