Nexus R5 VCU + LSx DBW Terminated Harness Injector Connector: EV6

The Ultimate LS Control System: Nexus R5 + DBW Harness

The Nexus R5 VCU + LSx DBW Terminated Harness Kit is the pinnacle of engine management for modern GM LS engine swaps. This package combines the immense power of the Nexus R5 Vehicle Control Unit (VCU) with a professionally terminated harness designed for Drive-By-Wire (DBW) LS engines. The harness is terminated with EV6 (USCAR) injector connectors, making it a direct fit for Gen IV engines like the LS2, LS3, and LS7. This system handles everything: engine control, power distribution (PDM), and data logging.

The Core of Command: Nexus R5 VCU

The Nexus R5 is not just an ECU; it’s a VCU. It integrates a 180A Power Distribution Module (PDM) directly into the unit, eliminating the need for external fuses and relays. The harness takes full advantage of this, routing high-current power directly to fuel pumps, fans, and coils. The R5 manages the complex DBW throttle control with redundancy and safety features, providing OEM-like driveability with motorsport performance.

Engineering the Nerve Center: The Terminated Harness

This harness is built to motorsport standards with high-temp wire and sealed connectors. It connects directly to the DBW pedal and throttle body, EV6 injectors, and standard LS sensors (Cam, Crank, MAP, IAT, CLT). It also includes alternator control and transmission support (4L60E/4L80E via CAN or direct wiring depending on config). This plug-and-play solution saves dozens of hours of wiring time and ensures a reliable, professional installation.
