The wire harness to the throttle position sensor is a well known issue on Polaris EFI machines. It will vibrate over time and break the wires either internally or externally and can be hard to diagnose. Many times it will throw a code but not always. Fix it now with our own version of the Polaris 2878498 harness repair kit. Simply cut off the old harness and use the included butt connectors or solder the connections to the new pigtail. Our pigtail fits perfectly to the Mikuni TPS sensor and has 6″ long wire leads. The last photo is for reference only, please ensure your TPS sensor looks the same before ordering. Fits the models listed below using the Mikuni throttle position sensors (3140173 and 3131705):

2006-13 Ranger 500 (EFI Models Only)
