Ford 7.3L DI Turbo Diesel PCM Connector C1027 Pinout - Powerstroke Wiring Diagram

This document is a connector pinout reference for the C1027 (gray) 104-pin Powertrain Control Module (PCM) connector used with the 7.3L DI Turbo diesel (Powerstroke) engine, as labeled '7.3L DIESEL.' The diagram shows the physical connector face with pins numbered 1 through 104 arranged in four rows, with callout leaders identifying circuit numbers and wire color codes (e.g., 315 P/O, 658 PK/LG, 977 P/W, 570 BK/W). Circuits marked with an asterisk apply only to trucks equipped with the E4OD automatic transmission. Below the diagram, a three-column table lists pins 1–32 with their circuit numbers, wire colors, and functions, including Transmission Shift Solenoids #1 and #2, Check Engine Light, Brake Warning Indicator, Idle Validation Switch, Generic Scan Tool Inputs, 4x4 Low Input, Auxiliary Powertrain Control Input, Ground, Torque Converter Clutch Solenoid, Clutch Pedal Position Switch, Transmission Control Switch, Exhaust Back Pressure Sensor, and Brake Pressure Switch. Many pins are listed as NOT USED. A reader can use this page to identify which PCM pin and wire color corresponds to each engine/transmission control circuit for diagnostics or wiring repair. Note that this appears to be one page of a multi-page set (a companion scan exists in the same album), likely covering additional pins beyond 32.
