Ford Taurus SHO 3.0L PCM Connector C191 60-Pin Pinout Diagram - Wire Colors

This document is a pinout diagram for connector C191, the 60-pin Powertrain Control Module (PCM) connector on a Ford 3.0L SHO engine. The drawing shows the physical face of the connector with three rows of numbered cavities (pins 1–20 across the top, 21–40 in the middle, and 41–60 along the bottom). Callout lines identify the circuit number and wire color code for each populated pin — for example, pin 1 is circuit 37 (Yellow), pin 3 is circuit 150 (Dark Green/White), pin 21 is circuit 68 (Orange/Black), pin 40 carries circuit 60 (Black/Light Green), and pin 60 is also circuit 60 (Black/Light Green). Several cavities are drawn filled/blackened, indicating unused positions with no circuit. Wire colors are given in standard Ford abbreviations (Y = yellow, LG = light green, DG = dark green, T = tan, PK = pink, BR = brown, O = orange, BK = black, DB = dark blue, GY = gray, R = red, W = white, LB = light blue, P = purple). A reader can use this diagram to locate any specific PCM pin, verify wiring by circuit number and color, and perform back-probing or continuity tests on the 3.0L SHO engine management harness.
