Power door conversion question

[joe231]

I have another question about converting to power. I'm going to get a pair of power doors off of a '85 tomorrow to convert my '80.
I realize I can just use the guts but my doors on my '80 have rust and someone repaired them by welding by the hinges and the door now lacks the adjustment needed to align properly with the fender and hood.
so my main question is about the wiring. does it unplug inside the cab somewhere, or do I need to cut wires? how many wires run to the drivers door, and how many run from the drivers to the passengers?
anyone have a schematic?
I would prefer not to stumble in blindly.
oh and also, do i have to pull the fenders to pull the doors?
Thanks for all the help, it is mucho appreciated.
