This document is page 3 of a 4-part wiring diagram set covering 1981 through 1983 Ford F-Series and Bronco trucks, published by Mitchell International (copyright 1994). It depicts the Instrument Panel and Underdash wiring. Components shown include the cruise control amplifier and servo unit, windshield wiper/washer switch, wiper governor, windshield wiper motor, air conditioning mode switch, blower motor, blower motor switch and resistor, speed cable sensor, clutch switch, printed circuit connectors (separate versions for gauge and non-gauge clusters), cigar lighter, glove box light and switch, clock, differential lock-out switch, 4-wheel drive indicator, ignition switch, headlight switch, dome light feed, fog light switch, hazard flasher, direction (turn signal) flasher, stop light switch, low brake warning switch, back-up light switch, horn switch (cruise control only), heated rear window switch/timer/indicator, and the combined horn/cruise/directional/hazard switch connector on the steering column. Wire color abbreviations (e.g., LT GRN-PPL, DK GRN-YEL, WHT-RED, BLK-LT GRN) are labeled throughout, along with tach-only and A/C-only circuit notations. A reader can trace instrument panel and underdash circuits and identify wire colors for these systems on 1981-1983 trucks.
