This document is one page of a Ford wiring circuit color-code reference chart, listing circuit numbers 701 through 834 with each circuit's description and its wire color (solid color or base color with stripe). Circuits 701-725 cover factory C.B. radio functions (squelch control, push to talk, up/down/scan switches, digit lines, noise blanker, relay drive, speaker connections). Circuits 730-749 cover the volt meter feed, distributor electronic control feed and breakerless ignition module wiring, speed control amplifier/servo circuits, air conditioner motor ground, fuel pump relay circuits, and radio receiver feeds. Later circuits (753-834) include heater/AC blower relay wiring, windshield wiper circuit breaker and motor, seat belt switch, engine alarm relay, brake pad switch, fuel pump primer and safety switches, neutral safety relay, stereo speaker and fader control wiring, fuel tank selector solenoid, stoplamp and trailer relay circuits, reverse relay feed, and speed-control servo vacuum solenoid and potentiometer circuits. Readers can use this chart to identify the wire color for a specific numbered circuit when tracing wiring in Ford vehicles of this era, for example: circuit 742 fuel pump relay to fuel pump is blue, and circuit 764 wiper circuit breaker to wiper motor is black with orange stripe. It is part of a multi-page wire color code set uploaded with a 1979 Ford Bronco wiring diagram album.
