Toyota Matrix 2ZR-FE | Toyota Corolla 2ZR-FE 2011-2014 Haltech Nexus Wiring Harness (BF29129)

The Matrix 2ZR-FE doesn't get much standalone ECU attention, and that's exactly what makes this harness worth having.

The Toyota Matrix 2ZR-FE is a practical platform with a capable engine, and standalone ECU support opens what the factory management keeps locked down. The Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
