Scion xB | Toyota Yaris Sedan & more 2006-2015 Haltech Nexus Wiring Harness (BF29049)

The xB 2ZR-FE is a practical, reliable engine that benefits from proper calibration more than most people give it credit for.

The Scion xB 2ZR-FE is a well-sorted platform with a loyal following, but the factory ECU limits what's accessible for serious modifications. 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.
