Nexus R5 + LSx Non DBW Terminated Harness

Complete PDM Control for Cable-Throttle LS Swaps

The Nexus R5 + LSx Non-DBW Terminated Harness Kit brings the advanced technology of the Nexus R5 VCU to classic cable-throttle GM LS engine builds. Ideal for Gen III engines (LS1, LS6, LQ4, LQ9) or race builds using a mechanical throttle body, this kit combines engine management and power distribution into one powerful package. The harness is terminated with EV1 injector connectors, matching the standard injectors found on most early LS engines.

Mastering the LS Swap

This system replaces the traditional ECU + Fuse Box setup. The Nexus R5 acts as the brain and the power center. The harness connects directly to the engine’s sensors and actuators while also providing high-current outputs for fuel pumps and fans, controlled directly by the VCU. This simplifies wiring, reduces weight, and provides advanced features like data logging, wideband O2 control, and traction control all in one unit.
