This document is a two-page pinout reference for connector C185, the Powertrain Control Module (PCM) connector on a Ford 5.0L engine equipped with either an E4OD or 4R70W automatic transmission. The left page shows a diagram of the 60-pin PCM connector with wire circuit numbers and color codes labeled around it (e.g., 37 (Y), 926 (LB/O), 570 (BK/W)), plus a table covering pins 1–30. The right page continues the table for pins 31–60. For each pin, the tables list the circuit number, wire color code, and circuit function — including power and grounds (B+ Keep Alive, PCM Case Ground), all eight fuel injector outputs, sensor inputs (VSS, ECT, MAF, TP, IAT, TFT, MLP, CKP, HO2S, Knock Sensor), transmission control circuits (Shift Solenoids #1 and #2, TCC Solenoid, Coast Clutch Solenoid, Electronic Pressure Control, Transmission Control Switch, TCIL), emissions controls (EGR, canister purge, AIRB/AIRD solenoids), and diagnostic links (VIP Data Link, MIL feed). Pins 24, 28, 43, 45, and 54 are marked NOT USED. A footnote indicates the Output Shaft Speed Sensor and Sensor Signal Return (pins 5 and 29) apply with the 4R70W transmission only. This is a valuable reference for diagnosing PCM, engine sensor, and transmission wiring issues.
