The Haltech Elite 2500 Non-DBW Terminated Harness Kit is tailored for GM GEN IV LSx engines like the LS2 and LS3, designed specifically for builds utilizing a cable-operated throttle (non-drive-by-wire). This plug-and-play solution combines the precision and performance of Haltech’s Elite 2500 ECU with a terminated engine harness, providing a fast, clean, and powerful engine management setup.
Ideal for high-performance and motorsport applications, this kit supports full race functions, robust data logging, and advanced tuning flexibility—enabling precise control over fuel, ignition, boost, and more.
Note: For off-road and competition use only. LS2 ignition coils and harnesses are not included.
