1987-89 Ford F-Series & Bronco Wiring Diagram - Starting, Charging, Wipers

This is page 12-49 from Chapter 12 (Chassis electrical system) of a repair manual, showing chassis wiring diagrams for 1987-89 Ford F-Series trucks and Bronco. The page contains five schematic diagrams. The top-left diagram covers the starting system, showing the ignition switch, park/neutral position switch (A/T), clutch interlock switch (M/T), starter relay, and starter motor circuits for both gasoline and diesel engines, including the auxiliary diesel battery. The top-right diagram covers the charging system for 1987 without A/C and 88-89 gasoline engines, including the alternator, fusible link J (14 GA-GRN), charge indicator in the instrument cluster, and choke heater (1987 5.8L/7.5L only). The middle-right diagram shows the charging system for 1987 with A/C and 88-89 diesel, including the alternator regulator, battery indicator, and radio condensor. The bottom-left diagram shows the power door lock circuit with a 30A circuit breaker (position 12), left/right door control switches, and door lock motors. The bottom-right diagram shows the interval windshield wiper/washer circuit with interval governor, washer pump, and wiper motor assembly. Wire colors (e.g., RED/LT BLU, BLK/ORG, PNK/YEL, DK BLU/WHT) are labeled throughout, making this useful for tracing starting, charging, door lock, and wiper circuits.
