Haltech Nexus R3 VCU + Plug and Pin Set (HT-193100)

A serious build running a Haltech Nexus R3 VCU is one of the strongest combinations in standalone engine management, and this kit delivers both halves at once: the ECU plus a matching plug and pin set for building your own harness exactly the way the chassis needs it. Engines with up to 8 cylinders or up to 4 rotors. Racing applications where advanced race features, data logging and power management control is required.

What You'll Feel

An engine that starts, idles, and drives like a factory car while the VCU handles engine management, power distribution, and dual wideband control natively. Fuel pump and thermofan control are direct, solid state, and logged.

The plug and pin set matters more than it looks: building a harness from scratch with the correct ECU-side connectors and terminals means factory-grade crimps, no adapters, and a loom routed exactly the way the chassis needs it. For a tube chassis car, a full rewire, or a motorsport build where every wire is specified, this is the right starting point.
