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.
