Ford EFI Wiring Diagram - EEC-IV Engine Control Module Pinout & Sensors

This document is a full-page EFI (electronic fuel injection) wiring schematic centered on the Ford EEC electronic engine control module. It shows the module's numbered connector pins (top row pins such as 1, 57, 37, 4, 2, 56, 16, 36, 51, 31, 22, 8, 30, 11, 33, 17, 21, 59, 58 and bottom row pins 48, 28, 9, 12, 29, 49, 6, 24, 27, 26, 47, 6, 45, 40, 60, 25, 43, 10, 7, 20, 46, 3) with wire color codes for each circuit. Components wired to the module include eight fuel injectors, the idle air bypass valve, fuel pump relay, EEC power relay, TFI ignition module, ignition coil, spark plugs, ignition suppression resistor, canister purge solenoid, thermactor air diverter and bypass solenoids, EGR control solenoid, inertia fuel shut-off, tank select switch and dual fuel pumps, heated oxygen sensor, knock sensor, power steering pressure switch (5.0L w/o E4OD), EGR valve position sensor, throttle position sensor, MAP sensor, intake air temp sensor, engine coolant temp sensor, and vehicle speed sensor. Power sources include fuse links N and W (hot at all times) and fuse 5 (15A, hot in run). E4OD-specific circuits and the VIP test connector are also shown.
