COMING SOON, available for order late summer 2022

Our new all-in-one engine and conversion harness streamlines and transforms the way K swaps are wired in the NA and NB Miata chassis. There are so many features and possible configurations packed into this new harness. Most notably:

-Two ECU options: Hondata Kpro4 and Haltech Elite 1500

-Haltech harnesses are now available for both cable and drive-by-wire throttle

-Multiple injector subharnesses available for any application

-Built-in fuse and relay box for simple, straightforward, and reliable wiring

-No more dash removal! The supplied sub-harness needs to be spliced to the gauge cluster pins, and one fuel pump wire run to the tank, but the dash can now remain in the vehicle

-Motorsports grade construction. 100% brand new connectors, Teflon coated wire, and Raychem DR-25 loom

-Haltech harnesses are pre-wired for the Bosch oil pressure and temperature sensor and CAN wideband controller

-Pre-wired for A/C, radiator fans, and flex fuel

-Configurations available for both K24A and K24Z sensors

This harness replaces the original KPro conversion harness, as well as the OEM engine harness (or KPower RWD harness).
