Reference · 1992-1996 BroncoAll 411 wiring diagrams
Powertrain Control Module C185 connector pinout chart for the 5.0L without E4OD/4R70W transmission, listing pins and circuit functions.
Part of 1992-1996 Ford Bronco Wiring Diagrams
This two-page document is the complete pinout reference for connector C185, the Powertrain Control Module (PCM) connector on a Ford 5.0L engine without the E4OD or 4R70W automatic transmission (i.e., manual/other transmission applications). It shows a labeled illustration of the 60-pin PCM connector with circuit numbers and wire color codes called out around the connector face, followed by tables listing every pin from 1 through 60 with its circuit number, wire color abbreviation, and circuit function. Key circuits include B+ Keep Alive power (pin 1, 37 Y), Vehicle Speed Sensor input/ground (pins 3 and 6), ECT sensor (pin 7), fuel pump monitor and enable (pins 8 and 22), VIP data link connector pins (9, 28, 48), MIL feed (17), IAC output (21), knock sensor (23), IAT input (pin 25, noted as early '94 only), reference voltage (26), HO2S input/ground (29, 49), SPOUT (36), MAP sensor input (45), TP sensor input (47), crankshaft position sensor pickup (56), injector bank drivers (58, 59), and grounds (20, 40, 60). Many pins are marked NOT USED. A reader can identify any PCM pin's wire color and function for diagnosis of engine management wiring.
