Ford Standard Wire Color Code Chart - Circuits 594-697 (1979 Bronco Wiring)

This document is one page of a Ford 'Standard Wire Color' code reference chart, listing circuit numbers 594 through 697 with each circuit's description and its standard wire color (including stripe colors). The circuits cover a wide range of vehicle systems: temperature transmitters and warning lamps, oil pressure safety and fuel pump primer switches, brake skid control (anti-skid) module wiring including wheel sensors and failure modules, EGR valve, speed sensor, oil and water temperature warning relays and lamps, tachometer and ignition coil circuits, ammeter shunt wiring, dual fuel tank selector switch/pump motor/fuel gauge wiring, tractor-trailer relay and marker lamp circuits, heated backlite switch, hydro-boost warning lamp, speed regulator (cruise) switch, and turn signal flasher circuits. For each circuit number, a reader can look up the standard factory wire color (e.g., circuit 640, ignition switch coil terminal to warning lamps, is red with yellow stripe; circuit 654, alternator shunt "A" terminal to ammeter, is yellow with black stripe). This page is part of a multi-page wiring color code set uploaded alongside other 1979 Ford Bronco wiring diagrams and connector references, useful for identifying and tracing factory harness wires by circuit number and color.
