This page (page 263) from a Haynes repair manual contains two wiring diagram sections for the 1979 Ford Bronco: Fig. 10.133 and Fig. 10.134 (both marked "continued"). The upper diagram (Fig. 10.133) covers the headlamp switch, ignition switch (positions: Start, Run, Off, Accessory), junction block, fuse links, and fuse panel connections (fuses F-2 through F-12), with a detailed right-hand legend listing circuit numbers, wire colors, and destinations, including power tailgate, trailer electric brake, ammeter, alternator/regulator, horn and speed control, interior and instrument panel illumination, courtesy lamps, emergency flasher, seatbelt warning, throttle solenoid/actuator, A/C-heater mode switch, windshield wiper/washer, backup lamps, turn signal flasher, radio, trailer battery feed and lamps relay, marker lamps relay, and 4-wheel drive indicator lamp. The lower diagram (Fig. 10.134) covers the charging and starting system: 40, 60, and 70 amp alternators, alternator regulators (with and without gauges), radio ignition interference capacitor, electric choke, 12-volt battery, starter motor relay, ammeter, and starter motor for 300/302/351/400 engines. Wire circuit numbers and color codes (e.g., 38 BK-R, 152 Y, 904 GR-R) and connector/splice identifiers (C-201, S-212, G-203, etc.) are shown throughout.
