Nexus Rebel LS Terminated Harness for Nexus Rebel LS ECU

The Backbone of Your LS Swap: Nexus Rebel LS Terminated Harness

The Haltech Nexus Rebel LS Main Terminated Harness is the central nervous system for your GM LS engine build. Designed exclusively for the Rebel LS ECU, this harness simplifies the complex task of wiring an LS engine by providing a modular, plug-and-play solution. It features breakouts for key engine sub-systems, allowing you to customize the harness to your specific engine generation (Gen III or IV) and component choices (injectors, coils, throttle type) by simply plugging in the appropriate sub-harnesses (sold separately).

Modular Flexibility

This main harness handles the core connections to the Rebel LS ECU and distributes signals to the various sub-harness connectors. It supports both EV1 and EV6/USCAR injector sub-harnesses, GM and Ford/Mercury coil sub-harnesses, and multiple alternator types. This modular approach means you buy one main harness and adapt it to fit an LS1, LS3, or even a hybrid build with ease. It is built with high-quality automotive-grade wire and connectors for maximum durability.
