Four ways to fit a Haltech

Plug-in

Keep the factory loom. Nexus Plug-in ECUs connect straight to it; Nexus S2 and S3 connect through an adaptor harness.

Nexus Rebel

A Rebel ECU with a harness already terminated for a popular engine. The quickest way from box to running car.

Terminated harness

A harness made for your engine (Barra, LS, 13B, RB, 2JZ and more) paired with an ECU. Less wiring than universal, more flexibility than Rebel.

Universal

Any universal ECU on a fully unterminated harness, for engine swaps, unusual combinations and from-scratch race cars.

ECUs

Every one supports flex fuel, closed-loop O2, launch control and boost control. The bigger the engine and the more you want to control, the further down this list you go.
