Ford Taurus/SHO Instrument Cluster Connector C250 Pinout - 3.0L & 3.4L SHO

This document is a connector pinout diagram and table for connector C250 (natural color), the instrument cluster connector, applicable to vehicles with the 3.0L 2V, 3.0L 4V, and 3.4L SHO engines — consistent with a Ford Taurus/SHO application. The upper portion shows the physical 16-pin connector face with each cavity numbered and labeled with its circuit number and wire color code (e.g., 57 BK, 932 GY/W, 640 R/Y, 1045 DB/W). Pins 4 and 11 are shown as not used. The lower table lists each pin, its circuit designation, and its function: pin 1 is ground; pin 2 is the high beam indicator input; pin 3 is the left turn lamp indicator output; pins 5 and 10 are power feeds (hot at all times and hot in start/run, respectively); pin 6 is the anti-theft indicator input; pins 7 and 8 are fuel pump/fuel gauge sender inputs; pin 9 is the engine coolant temperature sender input; pins 12–14 are generic electronic module inputs; pin 15 is a PCM input; and pin 16 is the instrument cluster dimming input. This is a useful reference for diagnosing gauge, indicator lamp, and cluster power/dimming problems, and for identifying wire colors when back-probing the cluster harness.
