Wire Pigtail LT1-TPS Sensor

The Wire Pigtail LT1-TPS Sensor from FAST Electronics is a precision connector kit designed for throttle position (TPS) sensor installation and repair across GM fuel injection platforms. This pigtail assembly serves as the critical electrical interface between your engine management system and the TPS sensor, enabling accurate fuel delivery calibration and engine performance optimization. Whether you're performing a complete fuel system retrofit, troubleshooting a faulty sensor signal, or upgrading a classic GM engine to modern EFI standards, this connector kit ensures reliable data communication between your vehicle's ECU and throttle body.

Built to OEM specifications, the Wire Pigtail LT1-TPS Sensor features factory-grade connectors and terminals that deliver consistent electrical conductivity without signal degradation. The pigtail design eliminates the need for custom wiring splices, reducing installation time and minimizing potential ground loop noise that can trigger diagnostic trouble codes. Compact at 2.85 x 2 x 4 inches and weighing just 0.14 lbs, this connector kit integrates seamlessly into tight engine bay configurations while maintaining professional-grade durability across temperature and vibration cycles typical of high-performance and street applications.

This connector kit is ideal for engine builders, performance tuners, and DIY enthusiasts working with GM TPI (Tuned Port Injection), LS-Series, and Gen V LT-Series powerplants. Whether you're installing a used LT1 engine in a classic chassis, upgrading carburetor-fed platforms to fuel injection, or replacing a damaged TPS harness, the Wire Pigtail LT1-TPS Sensor provides the OEM-correct interface your fuel management system demands. Proper TPS signal integrity is essential for idle quality, acceleration response, and emissions compliance—making this connector kit a non-negotiable component for any serious fuel injection installation or repair.
