Why Choose the HT-186400 Harness?

Built specifically for the JZ platform rather than adapted from a universal harness, the HT-186400 terminates directly to factory JZ sensors and connectors, cutting install time and reducing wiring errors compared to building a harness from scratch.

Tuning & fitment support

Buying the ECU is the start, not the end. We can talk you through which harness, sensors and accessories your combination actually needs, and point you toward tuners who know the platform.

Over 20 years of hands-on trade experience sits behind that advice — we build and run these cars ourselves.

Not sure which ECU or harness you need?

Haltech's range spans wire-in ECUs, plug-in ECUs, terminated harnesses and plug-and-play kits. The right choice depends on your engine, throttle type (cable or drive-by-wire) and injector connectors.

Send us your engine, model year and current setup and we'll confirm the correct part number before you buy.
