Haltech Nexus R3 VCU with Universal Wire-In Harness Kits
Haltech Nexus R3 with universal wire-in harness kits are ideal for dedicated race cars, engine swaps and custom wiring jobs. The harness has a set of VCU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are color-coded and clearly labeled. 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!
* Color-coded and labeled wires that match the detailed wiring diagram for a confusion free construction process.
* The wiring diagram is accompanied by the full ECU manual and software located on the USB key provided with the VCU, or downloadable from the Haltech website.
