Anybody know how to replace the wire set. Mine is totally fried in hinge area. I cut wires off and pulled out the body (easy side) plug. I can get a new set from dealer for abt 120 $...and was thinking to cut the top (body part portion out of new wire set and splice /solder the wires together at the hinge part after needle them all back into the rubber hose protector one by one... since I have no idea how to run the new wire through the rear gate door at my 2000 4 runner....
