Nexus R5 LSx Non DBW Terminated Harness

The Haltech Nexus R5 LSx Non DBW Terminated Harness is purpose-built for LSx engines running cable-operated throttle systems rather than electronic throttle control. This factory-terminated harness provides direct plug-and-play connectivity between your Nexus R5 ECU and LSx engine sensors, injectors and ignition components. Pre-terminated connections remove the labour and potential errors associated with custom pinning, while maintaining professional-grade wire specifications throughout. Ideal for performance builds, engine conversions and race applications where reliable harness construction is critical to consistent ECU operation.
