Can it be done, I have a RS no powerlock or power window and I find a ls in the junkyard with all that, can I install the power window and what do I need to take out the LS. If possable can any show me step by step lesson on the subject.
Sorry can’t show you…
Ideally you would take the doors and swap them out, if that’s not possible then you will need everything from inside the doors of the LS, including the wiring harness, you will need the door panels or at least the switches, you should also take at least the door harness to chassis harness plug, [chassis side] with at least 6" of wire, take the door lock module and power window relay and the associated under dash fuse box plugs, also with about 6" of wire, to tell which ones to take just look at your fuse box and take the ones you do not have.
Again the whole door is the best way, and at least the door harness chassis side plug and 6" of its wiring, you can make your own wire harness and two SPDT and one SPST automotive relays is all you need to make your own door lock “module” and power window “power supply relay”.
You will use some, [most] of the wires in the chassis plugs in your chassis plugs to make your harness.
I can walk you through the install, not that hard if you have a little patience, can take directions, know a little about 12V, have the tools, including a multimeter, and know how to use them.:stare:94
