I have a 1984 ford F350 crew cab with manual locks and windows. I go a steal of deal on some used doors out of a 89 f350 crew cab with power windows and door locks. The back doors are manual so issues there. But I am trying to find out how to wire up the new doors. Does any have a wiring diagram or know where I can get the wiring color coding to wire up the new doors. Has anyone done this kind of conversion? The wiring coming out of the door has 6 wires. Any help would be grateful.

 

The schematics are for a 88 but a 89 is probably the same.

You need the wiring harness that runs below the dash along the firewall that runs the length of the dash and contains the connectors to tap into the fuse block for the power windows and door lock circuit breakers at the fuse panel.
This is the wiring harness that goes from one door kick panel to the other door kick panel.

You can make the harness or go to the junk yard and get one if you don't have it. I would guess a wiring harness for a 87-91 truck would be plug and play.

 

What about a universal kit? Nu-Relics has some good ones.
