22-Position Connector – C131 (Green)

22-Position Connector – C131 (Green)

The C131 22-position green connector is used on Honda chassis as part of the engine-to-chassis harness interface. Located in the engine bay, this plug carries critical circuits between the engine harness and the chassis harness. Over time, factory connectors often become brittle, discolored, or develop poor contact from heat and vibration. Replacing it restores a secure OEM-style connection and ensures reliable electrical performance.

Ideal for restoration projects, this connector allows you to replace damaged or missing C131 plugs while maintaining correct factory fitment. It is also widely used in custom harness construction, providing a clean OEM-style interface when adapting or building looms. Supplied as a complete kit with the green connector housing, pins, and seals included, it provides everything needed for a proper factory-grade installation.
