Title: Power window and lock conversion with harness connections inside cab
Post by: Lowellguy1 on March 05, 2025, 09:49:09 am

Hello, I am restoring an 1987 Chevy R10.  I am converting it to power windows and locks from donor doors. I have acquired an original door harness for each side. When I ran the harness through A Plr. and into the cab on the passengers side there was an existing 6 plug female block/connector above the glovebox that looked to be correct for the passengers side harness. Is this possible it is pre wired for these options? On the drivers side I could not find the same plug. (I have yet to verify the plug and power on the passengers side). I did remove a doner harness a while back but my issue is that the plugs on each end of the donor (cab) harness are not correct.  Any help with locating the schematics as to how each side ties into the dash harness would be greatly appreciated.

All the power window/Lock harnesses I have removed were stand along and originated from the fusebox.

Some easy telltales are the power lock relay will be to the right of the steering column, there will also be a pink wire tapped into the fuse box with a circuit breaker. It will also have the bumped out kick panels to clear the wiring harness.
