Eliminate frustrating electrical issues and keep your Polaris running smoothly with this premium Bosch T-Map Sensor Pigtail Harness Repair Kit by Quad Logic. Designed as a direct replacement for the Polaris OEM harness, this repair kit addresses one of the most common problems found on Polaris EFI machines—the failure of the wire harness leading to the T-Map sensor. Over time, vibration and exposure can cause the original wires to fatigue, break internally or externally, and create inconsistent sensor readings or intermittent engine codes. This high-quality repair solution restores proper connection and ensures reliable performance of your fuel and air monitoring system, helping your engine run as intended.
Our harness is engineered to replace Polaris part numbers 2875542 and 2878494, providing a simple yet durable fix you can count on. Each kit includes a precision-molded plug that fits perfectly with Bosch 4-wire T-Map sensors (part numbers 2410422, 2411528, and 2411082). The pigtail features a waterproof boot that seals out moisture and protects the internal wires from dust, dirt, and debris. For installation, simply cut off the damaged connector and attach the new harness using the included butt connectors or by soldering for a more permanent repair. The plug snaps securely into place to maintain a solid electrical connection, ensuring dependable sensor performance for thousands of miles.
This T-Map sensor harness repair kit is compatible with a variety of Polaris models that use the Bosch 4-wire T-Map sensor configuration. Please note, for RZR Turbo models, this pigtail fits only with the Air Intake Duct T-Map setup.
