Clean Up Your Engine Bay with Mil-Spec Reliability
The factory MK4 Supra wiring is now decades old—brittle, prone to cracking, and never designed to handle modern standalone ECUs or high-horsepower sensor matrices. The RS Garage Pro Full Harness completely replaces your aging engine and chassis wiring with a single, ultra-clean, motorsport-grade electrical backbone.
