Door wiring harness laid out with labeled connectors for one-tou…

This is the right door harness from a '93 Bronco, but the procedure is the same for almost any reversible 12VDC motor. Cut the wires between the motor & the nearest control switch (R/Y and Y/R in this case). Connect a module's #1 (R) wire to one of the motor wires. Connect that module's #2 (Wh/Bk) wire and the other module's #4 (Y) wire to the harness side of the motor wire (from the switch). Connect the other module's 1,2,&4 wires likewise to the other motor wire. Splice both modules' #3 (Y/LG) wires into the vehicle power circuit (LB/Bk), and both modules' #5 (Bk) wires into the vehicle ground circuit (Bk).

Since this truck's door is normally only grounded through its hinges, I added a ground wire. There is also other additional wiring & modification for RKE, signal mirrors, under-mirror cornering/off-roading lights, & puddle lamps.
