New Premium Harness Builds

Current compatibility: Premium new harness builds are available for selected manual-transmission 2UZ-FE and 3UZ-FE applications, subject to ECU and project review. Automatic-transmission projects normally require an OEM-harness rebuild or reconfiguration and are quoted after review.

Custom application and compliance review

Our services are built for purpose-designed dune buggies, rock crawlers, off-highway safari vehicles, closed-course race cars, boats and custom bikes. They are not offered for vehicles registered, licensed or intended for street or highway use.

This application restriction does not authorize emissions tampering. We do not offer or support calibrations that disable emissions-control or OBD functions on EPA-certified vehicles or engines. Every project is reviewed for its original certification, finished-machine classification, intended use and applicable federal, state and local requirements before acceptance.

Tell us about the complete application so the workshop can confirm whether it is eligible before parts are shipped.
