This is page 10 of an aftermarket wiring reference booklet titled "FORD DIAGRAMS," showing generic Ford wiring information rather than a diagram for a specific model year. It contains four sections: (1) a Charging System diagram showing the alternator (terminals S, BAT, F), external voltage regulator (terminals I, A, S, F), battery, fusible link, and solenoid, with a wire-color legend (e.g., ALT PWR = RED, ALT EXCITOR = WHITE, OIL SENDING = LT BLUE/BLACK, TEMP SENDING = LT GREEN, COIL POS = PINK, TACHOMETER = PURPLE/WHITE, CHOKE = RED, AC COMPRESSOR = BLACK/WHITE, SOLENOID PWR = RED, IGN SW START = PURPLE); (2) an Ignition Switch Conversion table mapping factory Ford ignition switch wire colors to aftermarket harness colors; (3) a Steering Column Conversion table mapping turn signal, horn, brake switch, flasher, and hazard wire colors; and (4) a Ford Electronic Ignition diagram showing the DuraSpark distributor, ignition coil, starter solenoid, and electronic ignition module with wire colors (white, red, green, orange, purple, black). A reader can learn how to wire or convert a Ford charging system, DuraSpark ignition, and steering column to an aftermarket wiring harness using these color mappings.
