1978 Ford Bronco Chassis Wiring Diagram - Lighting, Charging & Wiper Circuits

This is a scanned page from a chassis electrical section of an automotive service manual, containing two full-page wiring diagrams printed sideways. The upper diagram covers the lighting, instrument panel, and heater/blower circuits, showing the hazard flasher, stop light switch, fuse box, blower motor and resistor, blower switch, instrument panel printed circuit connector, light switch, ignition switch, low brake switch, and the rear lighting (back-up, license, tail, direction, and marker lights), with wire color codes such as RED/GRN, WHT/RED, BLK/YEL, and BRN/YEL. The lower diagram covers the headlight, charging, starting, and windshield wiper circuits, including the headlights, horn relay, beam select switch, battery, fusible link, starter relay, starter, alternator and alternator regulator, distributor, ignition coil with noise filter, neutral/clutch safety switch, back-up light switch, windshield wiper motor and switch, and washer motor. Two 15-amp fuses are labeled for the back-up light and washer circuits. Numerous 'To...' callouts identify circuit destinations such as the ignition switch, EGR system, direction switch, and high beam indicator. The page footer reads 'CHASSIS ELECTRICAL.' A reader can use this page to trace wire colors and component connections for lighting, charging, starting, and wiper systems, though the scan's small sideways print limits full detail.
