BRE K24 Swap Harness Package for Mazda Miata (NA/NB)

** For a limited time, all orders will include a 100psi Pressure Sensor at no charge, a $99 value **

Version 2 of our race proven, truly Plug and Play* K-swap wiring package is now available!

Building upon the success of our Haltech Elite 1500 based harness package, all future harness packages will utilize the Haltech Nexus S2 ECU. Haltech's newest offering takes the reliability of the Elite 1500 and adds a built-in wideband controller, WiFi, greatly enhanced datalogging, plus more sensor inputs.

Harnesses can be built for either K24A2 or K24Z3 style sensor configurations, plus options for injector connectors, TPS/IACV or DBW configuration, and target chassis adapter. This information will be requested after the sale, before construction begins.

If you'd like to upgrade to the S3 or Nexus R3/R5 ECU instead, the harness can be easily reconfigured for those ECUs. Please email us before ordering for a formal quote.

Standard package includes:
BRE K24/Miata Wiring Harness
* Standard provisions include Flex Fuel, Oil Pressure, and Fuel Pressure sensors
Haltech Nexus S2 ECU
Bosch LSU 4.9 Wideband Oxygen Sensor

*** Special Order, please allow 2-4 weeks before shipping ***


* While NB applications are 100% plug and play, NA applications will require minor wiring for factory cluster and fuel pump operation. The changes required are simply due to the integrated nature of the NA engine/chassis wiring.
