1981-1983 Ford F-Series/Bronco Wiring Diagram - Fuse Block & Underdash (2 of 4)

This document is page 2 of a 4-page wiring diagram set titled 'FUSE BLOCK & UNDERDASH', covering 1981 through 1983 Ford F-Series and Bronco vehicles (Copyright © 1994, Mitchell International). The schematic shows underdash and engine-management wiring, including the engine electronic control processor (V-8 exc. 400 C.I.), throttle actuator, barometric pressure sensor, EEC power relay, mileage sensor (4.9L CA only), crankshaft timing sensor, coolant temp sensor, canister purge solenoid, EGR solenoids (vent, pressure, port), throttle angle position solenoid, air dump and carb float solenoids, electric choke, stepper motor, windshield wiper/washer motor, A/C clutch solenoid and thermostat, and the V.I.P. test connector. The lower-center section depicts the fuse box with circuit callouts such as HAZ./STOP, HEATER & A/C, 4WD CRUISE MOD, RADIO, POWER WINDOW, COURTESY LIGHT, HORN, INSTRUMENT LIGHTS, warning lights, horn relay (cruise control only), fog light relay, exterior light buzzer, and beam select switch. Wire runs are annotated with color codes (e.g., LT GRN-RED, DK GRN-YEL, TAN-WHT, RED-LT BLU). A reader can trace circuit paths and wire colors between the fuse block, EEC system, and underdash accessories, though individual fuse amperage ratings are not legible at this scan resolution.
