Throttle Position Sensor Pigtail Harness Repair Kit Replacement for Polaris RZR 570 800 – Replaces 2878498

This throttle position sensor (TPS) pigtail harness repair kit is designed to restore proper electrical connection on Polaris EFI models that commonly experience broken or internally damaged TPS wiring. Vibration, heat, and age can cause the factory harness to fail, leading to intermittent throttle response, fault codes, or drivability issues that are difficult to diagnose. This direct-fit replacement installs by cutting out the damaged connector and splicing in the new pigtail using the included connectors or solder. The harness features correct OE-style terminals, a secure connector body, and approximately 6 inches of wire leads for clean routing and installation. Designed to fit Mikuni throttle position sensors, this kit restores reliable signal transmission and proper throttle operation when used on the listed applications. Fits the models listed below using the Mikuni throttle position sensors (3140173 and 3131705): 2012-16 RZR 570 2011-14 RZR 800 (All Models).
