Ford Power Stroke Diesel PCM Connector Pinout Pins 33-104 - Wire Colors & Circuits
Reference · 1992-1996 BroncoAll 411 wiring diagrams
PCM connector pin-function chart continuing pins 33-104 with circuit numbers, wire colors, and assigned circuit functions.
Part of 1992-1996 Ford Bronco Wiring Diagrams
This document is a connector pinout reference table listing pins 33 through 104 of a powertrain control module (PCM) connector, apparently for a Ford Power Stroke diesel application (based on the upload filename and circuit functions such as Injection Pressure Regulator, Injection Control Pressure Sensor, Glow Plug Control Output, and Wait to Start Output). For each pin the table gives the circuit number, wire color code (e.g., 676 PK/O, 358 LG/BK, 570 BK/W), and the circuit function. Notable circuits include the Vehicle Speed Sensor (pins 33, 58), MAP Sensor (34), Transmission Fluid Temperature Sensor (37), CAM Position Sensor (49) and its return (65), IDM Signal Input (48) and IDM Enable Output (70), Power Inputs (71, 97), Grounds (51, 76, 77, 103), Keep Alive Power Input (55), Accelerator Pedal Position Sensor (89), Brake ON/OFF Switch Input (92), Fuel Delivery Command Signal Output (95), Glow Plug Control Output (101), and Wait to Start Output (80). Circuits marked with an asterisk (923, 924, 199, 911, 925) apply only with the E4OD transmission, per the footnote '* W/E4OD TRANSMISSION.' Many pins are marked NOT USED. Readers can use this to identify wire colors and functions at each PCM pin for diagnostics and wiring repairs.

Frequently asked questions
- What wire color is the Glow Plug Control Output on the PCM?
- Pin 101, circuit 1086 (P/O: purple/orange), is the Glow Plug Control Output.
- Which PCM pins are grounds?
- Pins 51, 76, 77, and 103 are grounds, all circuit 570 (BK/W: black/white). Pin 33, circuit 676 (PK/O), is the Vehicle Speed Sensor Ground, and pin 40, circuit 848 (DG/O), is the Speed Control Ground.
- What do the asterisked circuits in this pinout mean?
- Circuits marked with an asterisk (e.g., *923, *924, *199, *911, *925) apply with the E4OD transmission, per the footnote '* W/E4OD TRANSMISSION.'
- Which pin is the Injection Pressure Regulator?
- Pin 83, circuit 552 (Y/R: yellow/red), is the Injection Pressure Regulator.
- What pins provide power to the PCM?
- Pin 71 and pin 97 are both Power Inputs on circuit 361 (R: red), and pin 55, circuit 37 (Y: yellow), is the Keep Alive Power Input.
