VCU Overview
Nexus R3 combines the functionality of a power distribution module, a data logger, a wideband controller and a state-of-the art engine management system in one powerful device we call a VCU (Vehicle Control Unit).
Harness Overview
Ideal for dedicated race cars, engine swaps and custom wiring jobs. The Universal Wire-in Harness has a set of VCU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are colour coded and clearly labelled. Connect your Haltech VCU to the terminated end and follow your wiring diagram for all the engine connections. Load your base map and you're ready to go!
