Manual wiring diagram of the 1985 Ford F-Series/Bronco chassis electrical system with color-coded circuits and connectors.
Part of 1980-1986 Ford Bronco Wiring Diagrams
This is a scanned page (6-69) from a chassis electrical section of an automotive service manual, showing Figure 108: the wiring diagram for the 1985 Ford F-Series pickup and Bronco, section one. The diagram traces circuits for the windshield wiper/washer switch and motor, blower motor and resistor with blower switch (H-M-L), coolant temperature and oil pressure switches, seat belt timer/warning buzzer, instrument panel printed circuit connector (with wire colors such as RED, LT.GRN, RED/WHT, BLU/RED, WHT/RED, RED/YEL, GRN/WHT), the light switch, ignition switch, stop light switch, back-up light switch, hazard and directional flashers, low brake switch, and the directional/horn/hazard switch. Exterior lighting circuits include right and left marker lights, tail lights, direction lights, back-up lights, and license lights. A fuse box legend lists positions and ratings: HAZ/STOP LTS 20A, WIPER 10A, RADIO 10A, AUX FUEL TANK 10A, PWR WDS CB, HEATER CB, INST LTS 5A, EMISSION 15A, TAIL LT 15A, PWR ACCY CB, CTSY LT 15A, and HORN/CIG 20A. Wire color codes are labeled throughout, making this useful for tracing chassis electrical circuits on 1985 F-Series and Bronco trucks (and closely related model years).
