I have purchased a 99 Quadcab ranger with manual locks and windows. I have found a donor truck that has power windows and locks . Anyone have any idea what all is involved in doing this swap. Are the wires for the switches already there, or will I need the wiring harness

 

I would start comparing the mounting holes, take pictures of both doors without the interior panels... compare, see if you can see any part numbers on the electric parts you have, try comparing the part numbers on some of the Part Sites or at least see if the Electric Motors are the same numbers as what would be used in the '99 if it did have Power Windows.

The other option is to start taking the parts out of the Electric Doors and see if the mount in yours.

If you are talking actually switching the doors, start measuring.
