Listing is for one OEM 4-Way Harness Connector. This Connector replaces the one on the vehicle harness, not the sensor itself. Connector comes fully assembled with 4 color Non-Coded wires pre-installed. Non-Coded means that the wire coloring will not match any specific wire harness. Please use the Compatibility tool to verify filament as not all Sub-Models are supported. If you have any questions about this connector or any other please feel free to contact me.
