Elite 2000/2500 Non DBW Terminated Wire Harness

The Elite 2000/2500 Non DBW Terminated Wire Harness from HALTECH is a complete engine wiring solution engineered for GM LS-series engine swaps and non drive-by-wire applications. This harness eliminates the complexity of factory wiring by providing a pre-terminated, plug-and-play alternative that integrates seamlessly with the Elite 2000/2500 ECU platform. Whether you're performing a LS engine conversion on a cable-operated throttle body or rebuilding a classic with modern fuel injection, this harness delivers the reliability and simplicity that serious builders demand.

The Elite 2000/2500 Non DBW Terminated Wire Harness features fully terminated connectors and circuits optimized for traditional mechanical throttle cable configurations, eliminating the need for custom wire routing or terminal splicing. Its design accommodates injector drivers, coil packs, fuel pump relays, and all essential LS-series engine sensors—oxygen sensors, coolant temperature, intake air temperature, and crank/cam position inputs—without requiring proprietary adapters. The harness ships at 6.29 pounds and measures 14.15 x 4.9 x 16.95 inches, providing a compact footprint suitable for tight engine bays while maintaining proper strain relief and shielding for noise-free operation across the entire RPM range.

Builders converting first-generation LS powerplants into muscle cars, trucks, and custom hot rods benefit most from this harness, as it sidesteps the complexity of reverse-engineering factory DBW (drive-by-wire) pinouts and reduces installation time by 4–6 hours compared to hand-terminated alternatives. Installation is straightforward: connect the main harness to your Elite ECU, terminate sensor and actuator leads to their respective engine components, and route power and ground to the battery. This harness is purpose-built for carbureted or cable-operated fuel injection applications and is fully compatible with naturally aspirated and supercharged LS-series engines when paired with appropriate fuel system and ignition components.
