What connector is C250?

C250 is the connector for the standard instrument cluster; it is an 18-pin connector with pins 1 and 18 at the top and 9 and 10 at the bottom.

Which pin on C250 is the fuel sender?

Pin 2, circuit 29 with a Yellow/White (Y/W) wire, is the Fuel Sender circuit.

Where does the Vehicle Speed Sensor (VSS) connect on the standard cluster?

Pin 3, circuit 150 with a Dark Green/White (DG/W) wire, is the Vehicle Speed Sensor (VSS) input.

Which pins are power and ground on the C250 standard cluster connector?

Pin 16 is power (circuit 640, R/Y). Grounds are pin 4 (57 BK), pin 17 (57 BK), and pin 18 (359 GY/R).

Which pins on C250 are not used?

Pins 1, 7, 8, 9, and 13 are listed as NOT USED.

This document is a connector pinout reference for connector C250, the standard instrument cluster connector. It includes a diagram of the 18-pin connector face showing pin orientation (pins 1/18 at top, 9/10 at bottom) with circuit numbers and wire colors called out for each populated cavity. Below the diagram, a table lists all 18 pins with their circuit numbers, wire colors, and functions. Key circuits include: pin 2 — circuit 29 (Y/W) Fuel Sender; pin 3 — circuit 150 (DG/W) Vehicle Speed Sensor (VSS); pins 4, 17, and 18 — grounds (57 BK, 57 BK, 359 GY/R); pins 5 and 10 — circuit 19 (LB/R) Illumination; pin 6 — circuit 2 (W/LB) Right Turn Indicator; pin 11 — circuit 871 (Y) Passive Restraint Module; pin 12 — circuit 31 (W/R) Oil Pressure Switch; pin 14 — circuit 606 (W/LB) Anti-lock Brake Control Module; pin 15 — circuit 627 (BK/O) Door Ajar Switches; and pin 16 — circuit 640 (R/Y) Power. Pins 1, 7, 8, 9, and 13 are not used. This is useful for diagnosing gauge, illumination, VSS, or cluster power/ground issues on vehicles using this standard (non-electronic) cluster.
