1987-1996 Ford Bronco Tailgate Power Window Wiring Diagram - Wire Colors

This document is a hand-drawn wiring diagram titled "87-96 Ford Bronco tailgate window power wiring diagram," credited to Ed Huggler II. It illustrates the electrical circuit for the power tailgate window on 1987-1996 Ford Broncos. Power originates from two circuit breakers (labeled #14 and #12), feeding the circuit via lt blue-black and black-white wires. The tailgate key switch, with Down and Up buttons, routes signals through pink-lt green and pink-lt blue wires to the Down relay and Up relay, which are grounded through a black wire to Ground. Downstream of the key switch, a tan-black wire passes through the tailgate latch switch (a safety interlock in the latch), then continues as a red-yellow wire to the window motor. A yellow-red wire provides the return/other leg of the motor circuit. The diagram identifies every wire color code in the circuit, the relative positions of the relays, switches, breakers, motor, and ground point. A reader can use this to trace the tailgate power window circuit, identify which wire colors correspond to up/down functions, and diagnose failures in the tailgate glass system such as bad relays, a faulty latch switch, key switch problems, or breaker issues.
