Ford C251 Instrument Cluster Connector Pinout - 16-Pin Wiring Diagram

This document is a connector pinout diagram for connector C251 (Natural color), the instrument cluster connector, apparently from a Ford factory wiring/EVTM reference. The upper portion shows a drawing of the 16-pin connector body with each cavity numbered 1 through 16 and labeled with its circuit number and wire color code (e.g., pin 1 = circuit 2, White/Light Blue; pin 6 = circuit 397, Black/White). Below the drawing, a three-column table lists Pin Number, Circuit (number and color), and Circuit Function for all 16 pins. Functions covered include the right turn indicator, low coolant indicator feed, air bag indicator feed, brake indicator feed, anti-lock (ABS) indicator feed, tachometer feed, low engine oil indicator, illumination lamps feed, fasten belts indicator, engine oil pressure gauge feed, two B+ power inputs (circuit 640, R/Y on pins 9 and 13), and four grounds (pins 6, 8, 14, 16). A reader can use this to identify which wire and color at the instrument cluster connector serves each gauge or warning lamp, useful for diagnosing cluster, gauge, or indicator lamp problems, or for cluster swaps and custom wiring. The document itself does not state a year, make, or model; the filename suggests it may pertain to a 1995 Mustang instrument panel.
