Elite 2500 DBW Ready Terminated Wire Harness

The Elite 2500 DBW Ready Terminated Wire Harness from Haltech is a fully assembled, plug-and-play engine wiring solution engineered specifically for GM LS-series engine swaps and high-performance builds requiring drive-by-wire compatibility. This harness eliminates the guesswork of custom wiring by delivering a pre-terminated main harness that integrates seamlessly with DBW throttle bodies and modern fuel injection systems, making it an essential component for LS engine conversions in non-OEM platforms.

Built with terminated connectors and quality shielding throughout, the Elite 2500 DBW Ready harness minimizes electromagnetic interference and ensures reliable signal transmission between engine sensors, injectors, ignition coils, and the ECU. The pre-terminated design means each connector is factory-sealed and positioned for LS applications, reducing assembly time and the risk of continuity errors that plague custom loom builds. The harness accommodates all necessary circuits for fuel pump control, idle air control, MAF sensors, oxygen sensors, and accessory outputs, providing a complete electrical backbone for sophisticated engine management.

This harness is ideal for engine builders, swap specialists, and serious enthusiasts installing LS powerplants in classic cars, kit cars, or non-OEM chassis where OEM wiring is incompatible or inadequate. Its DBW-ready configuration supports modern drive-by-wire throttle bodies without additional adapters, making it compatible with late-model LS variants and aftermarket ECU tuning platforms. With a compact footprint and professional-grade construction, the Elite 2500 terminates the debate over reliability and saves countless hours of troubleshooting during installation and startup.
