This document is a portion of a Ford EEC/powertrain wiring diagram showing connector faces and pin assignments for sensors and actuators related to the E4OD automatic transmission and engine management. The highlighted section details the E4OD Transmission Vehicle Harness Connector with its circuits and EEC processor pin numbers: TOT (pin 7), CCS (55), CCC (53), SS1 (52), SS2 (19), EPC (38), and EPC PWR (37/57). Across the top, connector faces are shown for the Manual Lever Position (MLP) sensor (pin 30), Heated Exhaust Gas Oxygen (HEGO) sensor (PWR GND, IGN RUN, HEGO GND 49, HEGO 29), Engine Coolant Temp (ECT) sensor (pin 7), Air Charge Temp (ACT) sensor (pin 25), and Throttle Position (TP) sensor (pin 47). Also depicted are the Brake On/Off (BOO) switch (BATT+, pin 2), 4x4L input (pin 12), the Overdrive Cancel Switch/Lamp pigtail connector (OCIL 32, OCS 41), the PSOM module connector (PSOM+ pin 3, PSOM- pin 6, 60-pin), fuel injectors INJ-1 through INJ-8 (pins 58/59) for cylinders 1-8, and the ISC (pin 21). A reader can identify connector shapes and which EEC pin each transmission and sensor circuit connects to.
