1990 Ford 7.5L Engine Component Location View 151-7 - Connectors & Relays

This is page 151-7, "Component Location View," from a 1990 Ford Electrical & Vacuum Troubleshooting Manual (EVTM), figure reference FPS-12129-90 (7 of 12). It is the second of two component location illustrations for the 7.5L engine, showing a top-down line drawing of the engine compartment overlaid on a locator grid (columns 1-10, rows A-F). Callout lines identify the physical locations of electrical components and wiring connectors, including the fuel injectors, ignition coil, radio capacitor, blower resistors, canister purge solenoid, idle air bypass valve, coolant temperature sender, A/C clutch field coil, dual brake warning switch, EEC power relay, fuel pump relay, washer pump, horns, and the left-hand park and turn lamp. Numbered connectors and grounds identified include C100, C101, C102, C104, C105, C122, C133, C134, C139, C152, C153, C203, and grounds G101, G102, and G104. A boxed note warns not to use the illustration and grid for reporting vehicle repair locations. A reader can use this page to physically locate these connectors, relays, sensors, and grounds in the engine bay of a 7.5L-equipped 1990 Ford truck when diagnosing wiring problems.
