LS 3-Wire Pigtail Thrott le Position Sensor

The LS 3-Wire Pigtail Throttle Position Sensor harness connector is an essential component for LS engine swaps and custom engine management installations. Built by ICT Billet, a manufacturer known for precision intake manifolds and engine bay components, this pigtail adapter bridges the gap between OEM throttle position sensors and modern ECU tuning platforms. Whether you're retrofitting a standalone ECU, upgrading to a carbureted setup, or integrating a cable-driven throttle body into a fuel-injected LS platform, this connector eliminates the frustration of incompatible wiring and sensor mismatches that plague DIY builders.

This three-wire harness is engineered to maintain proper electrical continuity and signal integrity between your throttle position sensor and your engine control unit. The pigtail design allows you to adapt OEM or aftermarket sensors without cutting factory wiring, preserving the option to revert to stock configurations if needed. The compact 2 x 0.5 x 3-inch form factor fits neatly in tight engine bays, and at just 0.1 lbs, adds no meaningful weight to your build. ICT Billet's attention to connector quality ensures reliable throttle response calibration and prevents sensor dropout or intermittent code faults that can plague poorly assembled harnesses.

LS engine builders working with Holley, Edelbrock, or other standalone ECU platforms will find this adapter indispensable when adapting modern sensors to older wiring harnesses or when mixing OEM and aftermarket components. Off-road fabricators, street rod shops, and tuners performing engine conversions benefit from the standardized three-wire configuration, which supports both analog and digital sensor types. Installation is straightforward—simply splice the pigtail into your throttle sensor circuit and secure your connector, then calibrate your ECU's throttle tables. Compatible with all LS-series engines (LS1, LS2, LS3, LS7, and variants), this connector becomes a foundation piece in any professional-grade engine management system.
