Fitting 1960-66 power windows is a one-door-at-a-time job, and the glass still runs in the factory channel afterwards. Our kit for 1960-66 doors replaces the crank regulator in these doors with an electric regulator and motor. The door changed for 1964, so there are two mounting diagrams below. First, identify which door you have. Then follow the matching diagram, and use the wiring notes further down before the panel goes back on.

Tools you will need
- Door panel removal tool and basic hand tools
- Drill with a 5/32″ bit and a 10-32 tap for the harness clip
- 7/8″ hole saw or step bit for the kick panel grommet
- Wire strippers, crimps and a test light or multimeter
Wiring and switch tips
- First, disconnect the battery before any wire goes into the door.
- Bench test each motor on the truck battery before the regulator goes in. It is far easier to swap a motor on the bench than inside a door.
- Route the harness through the hinge side with a grommet, and leave enough slack for the door to open fully without pulling on the wire.
- Fuse the circuit at the source. A 20 amp fuse covers a pair of power window motors on most kits.
- Finally, test the switches before the door panel goes back on. If a window runs the wrong way, swap the two motor wires at the switch.
1960-66 power windows fitment notes
Every one of these doors has a different history, so expect to trim a bracket or move a hole once in a while. Also, run the glass up and down by hand before the motor is connected, because a stiff channel will stall a motor that is otherwise fine. New felt run channels make a bigger difference than most people expect. The rest of the door hardware for the same cab is in our 60-66 truck parts collection.
Mounting differs between the 1960-63 and 1964-66 doors, so identify yours first. If you are not sure which year your cab is, run the serial number through our VIN decoder. Firewall and cowl panels, billet hood hinges and door hardware for this cab are in our 60-66 truck parts collection.
