The Ultimate Gen III LS Swap Solution: Rebel LS ECU Kit
Simplify your Gen III LS engine swap with the Haltech Nexus Rebel LS Kit. Designed specifically for the 24x crank trigger engines (LS1, LS6, early truck Vortec), this package provides a complete, easy-to-install engine management system. The Rebel LS ECU integrates power distribution, meaning no separate fuse box or relays are required—just power, ground, and ignition switch connections to get started.
Cable Throttle & EV1 Ready
This kit is tailored for mechanical cable throttle setups and includes the sub-harness for Bosch EV1 style injectors, matching the factory hardware of the Gen III platform. It includes the main harness, alternator adaptors, and a knock sensor adaptor specifically for the Gen III valley-mounted sensors. A Bosch LSU 4.9 wideband sensor kit is included for accurate air/fuel ratio monitoring and closed-loop control. With the Rebel LS, you get advanced features like Wi-Fi tuning and data logging in a package that is incredibly easy to install.
