This two-page reference documents connector C185, the 104-pin Powertrain Control Module (PCM) connector for a Ford 5.0L engine. The left page is a pin-face diagram of the gray C185 connector showing all 104 cavity positions with callouts giving each populated pin's circuit number and wire color code (e.g., 555 (T), 570 (BK/W), 351 (BR/W)). The right page is a complete pinout table listing every pin from 1 to 104 with its circuit number, wire color, and circuit function. Functions include transmission shift solenoids #1 and #2, MIL, data link (FEPS, +, −), fuel pump monitor and enable, all eight fuel injector outputs, ignition/spark signals (IDM, SPOUT), sensor inputs (ECT, IAT, TFT, CKP, TP, MAF, VSS, misfire, HEGO sensors #11/#12/#21 and their heater monitors), EGR and EVAP controls, EPC, IAC valve output, TCC and coast clutch solenoids (E4OD only), OSS (4R70W only), grounds, keep-alive power, and power feeds hot in Start or Run. Many pins are marked NOT USED. A reader can use this to identify any PCM pin's wire color and function for diagnostics or wiring repair on a 5.0L application.
