Haltech GM GEN III LS1 & LS6 (Non DBW) Elite 2000/2500 Terminated Harness w/EV1 Injector Connectors

This terminated harness from Haltech is built with a robust, high-temperature rated wire that can handle the heat under the hood. It's specifically designed to connect your Haltech Elite 2000 or 2500 ECU to a GM Gen III LS1 or LS6 engine that does not use a Drive-by-Wire (DBW) throttle system. The EV1 injector connectors ensure a secure and reliable connection to your fuel injectors, which is crucial for consistent fuel delivery and engine performance.

When you're installing a Haltech ECU, having a harness that's made for the job makes a huge difference. This harness is terminated, meaning all the connections are already made to the ECU side, simplifying your installation process significantly. You won't have to spend hours crimping pins or figuring out which wire goes where on the ECU connector. The wiring itself is high-strand count, which helps resist vibration and fatigue, ensuring long-term reliability in a demanding engine bay. It's a well-built piece that takes the guesswork out of wiring your LS engine to a modern standalone ECU.

This harness is designed for non-DBW applications, so it's important to confirm your throttle body setup before ordering. If your LS1 or LS6 uses a traditional cable-driven throttle, this harness will integrate seamlessly. It's a key component for anyone looking to upgrade their engine management system and unlock the full potential of their Gen III LS powerplant.
