1979 Ford Bronco Wiring Diagram - Ignition, Starter & Instrument Gauges

This is page 264 from a Haynes repair manual showing two continued sections of the factory-style wiring diagram for the 1979 Ford Bronco (Fig. 10.135 and Fig. 10.136). The upper diagram (Fig. 10.135) covers the starting and ignition systems: the 12-volt battery, starter motor relay, starter motor (labeled for 300, 302, 351 & 400 engines), auxiliary 12-volt battery, accessory safety relay, the 8-cylinder 351/400 breakerless distributor, ignition coil, breakerless ignition modulator, radio ignition interference capacitor, transmission gear shift neutral switch, and ammeter, with fuse links and wire circuit numbers/colors (e.g., 37 BK-Y, 38 BK-R, 32 R-BL, 16 R-GR, 526 BK-W). The lower diagram (Fig. 10.136) covers the instrument cluster and warning circuits: ignition switch (positions S-Start, R-Run, O-Off, A-Accy), dual brake warning indicator lamp and switch, oil pressure warning lamp and switch, alternator warning indicator lamp, fuel gauge and fuel gauge sender, water temperature gauge and sender, radio receiver suppression choke, and instrument cluster voltage regulator (C/V unit). Connector numbers (C-2xx, C-3xx, C-1xxx series), splices (S-xxx), grounds (G-203, G-1201), fuses (F-3, F-5, F-10), and resistance specs (1.05 to 1.15 ohms; 8 to 9 ohms) are shown, with distinctions between 'with gages' and 'without gages' configurations.
