This document is page 30-3 of a 1995 Ford Bronco wiring/connector reference covering the E4OD automatic transmission. It shows the pinout of connector C1048 (gray), the main harness connector at the E4OD transmission. A drawing of the 12-cavity connector face is shown with wire circuit numbers and color codes called out at each cavity: 361 (R), 925 (W/Y), 923 (O/BK), 359 (GY/R) at the top, and 315 (P/O), 480 (P/Y), 361 (R), 237 (O/Y), 924 (BR/O) at the bottom. A table lists each of the 12 pins with its circuit number, wire color, and function: Pin 1 — 361 (R) Power from PCM Relay; Pin 2 — 315 (P/O) Shift Solenoid #2 Output; Pin 3 — 237 (O/Y) Shift Solenoid #1 Output; Pin 4 — 480 (P/Y) Torque Converter Clutch Control Solenoid; Pin 5 — 924 (BR/O) Coast Clutch Solenoid; Pin 7 — 923 (O/BK) Transmission Fluid Temperature Sensor; Pin 8 — 359 (GY/R) Sensor Signal Return; Pin 11 — 925 (W/Y) Electronic Pressure Control; Pin 12 — 361 (R) Electronic Pressure Control Power. Pins 6, 9 and 10 are marked NOT USED. Useful for diagnosing solenoid, TFT sensor, and EPC circuit problems at the transmission connector.
