I have an 89 Suburban which has doors which are not original. The New doors have power windows and locks but are not wired at all. I have looked for the harness they connect to but it is not present. Does anyone have any experience wiring these doors manually. There are two sets of wires. One is Orange and Grey this is heavy gauge and I believe door locks. The other pair is Orange (black line), Blue and Black (white line)..I believe these are window. Any suggestions would be appreciated.

since the doors are normally wired into a loop they will need relays and complete circuits to function. I suggest finding a wiring diagram for your vehicle and see if you can add the needed stuff to it.
