Restore reliability and performance to your Polaris EFI system with this premium Bosch T-MAP Sensor Pigtail Harness Repair Kit, engineered as a direct replacement for Polaris part numbers 2875542 and 2878494. This high-quality wire harness solution addresses one of the most common electrical issues found on Polaris EFI machines — damaged or broken wires caused by vibration, heat, and long-term wear. When the T-MAP sensor harness begins to fail, it can result in poor engine performance, erratic idling, or even unexpected fault codes that can be difficult to trace. Our replacement harness eliminates these problems by providing a secure, durable, and weather-resistant connection that ensures consistent sensor performance and accurate air/fuel readings.
Each kit includes a precisely molded connector that fits perfectly onto Bosch 4-wire T-MAP sensors (part numbers 2410422, 2411528, and 2411082). The plug is equipped with a waterproof boot that protects the wiring from moisture, dirt, and debris, ensuring a long service life even in harsh riding environments. Installation is simple — just remove the damaged factory connector and attach the new harness using the provided butt connectors, or for a more permanent solution, solder the connections. No special tools are required, making this an easy and affordable repair for both DIY enthusiasts and professional mechanics.
Designed specifically for Polaris RZR 800 and other compatible models using Bosch T-MAP sensors, this harness repair kit restores the reliability and accuracy of your machine’s EFI system. It’s the perfect solution to eliminate intermittent sensor faults, prevent unexpected check engine lights, and ensure smooth engine performance. Built to OEM specifications and tested for durability, this pigtail harness offers a precise fit, superior conductivity, and lasting protection against vibration damage.
