GM truck interior wiring 88-98

[BOOOGHAR]

Im getting a full size truck that has manuel windows and door locks and want to switch over to power windows and locks (im going to buy another set of doors) but im wondering if a wiring harness is already in place or do I need to get the harness from the donor truck

not sure , never swapped it , but I doubt it - wait till you see the f ucked up regulator/plate inside the door ..many a day of fun with those for me

hopefully it's the same as the prior generation. In the 81-7 trucks, there's a loom that runs from cab side to cab side - plugs into the fuse panel, and into each door power. I vaguely remember a friend converting their 89 to PW/PDL, and I think he had to get the entire dash harness...

If you need a service book (chilton's) with wiring harness diagrams, I have an extra and it's yours for the asking (pm me your address)
