AI caption February 2013 · Photo 52 of 104

This document is one page of a Ford wiring circuit color-code reference table, listing circuit numbers 208 through 373 with a description of each circuit and its corresponding wire color. Each row identifies the two connection points of the circuit (e.g., 'STOPLAMP SW. TO RELAY', 'FUEL GAUGE INDICATOR TO TANK SENDING UNIT') and the insulation color, including solid colors and striped combinations such as RED-BLACK STRIPE or YELLOW-BLACK STRIPE. Systems covered include water temperature and oil level warning circuits, heater blower motor speeds (low/medium/high), windshield washer and wiper, turn signals, stoplamps, alternator/voltage regulator circuits, fast idle relay and air conditioning compressor clutch circuits, power window regulator circuits, speed control (clicker relay, brain, brake switch), 3-speed axle and axle lockout circuits, and fuse panel accessory feeds. A reader can use this table to identify a wire's function by its circuit number or trace a circuit by its wire color when diagnosing electrical problems. The page appears to be from a multi-page set of wiring color code pages scanned from a Ford service reference; no year, model, or part number is stated on this page itself.
