The Haltech HT-186010 i6 Sumitomo (Denso) Primary Injector Harness is a purpose-built sub-harness designed to connect six Denso-style fuel injectors directly to your Haltech Nexus engine management system. Engineered specifically to suit Nexus Rebel JZ main terminated harnesses, this injector harness ensures reliable injector control, accurate cylinder identification, and clean signal integrity in high-performance applications.

Each injector connector is clearly labelled, making installation fast and eliminating wiring errors during engine assembly or service. This is especially important in turbocharged and competition engines where precise fuel delivery is critical to power output, drivability, and engine safety.

Manufactured to Haltech’s motorsport-grade standards, this harness is ideal for street, track, and race Toyota JZ engine builds using Sumitomo (Denso) injector connectors.

Haltech products come with a limited 12-month warranty covering defects in materials and workmanship from the date of purchase.

Dispatch & delivery

If the item is in stock at our Perth warehouse or at Haltech, it ships same or next business day.

Not every product is held in stock, including at Haltech. Items that need to be built or restocked can take up to 4 weeks.

If you want a firm lead time before you order, get in touch and we'll confirm it for you.

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.
