Supra Power Interface: Nexus S3 Adaptor Harness for JZA80
Unleash the full potential of your Toyota Supra JZA80 (2JZ-GTE Non-VVTi) with the Haltech Nexus S3 Plug ‘n’ Play Adapter Harness. This high-quality adaptor allows you to connect a Haltech Nexus S3 ECU directly to the factory engine wiring harness, replacing the aging stock ECU with a modern powerhouse. This is the ultimate upgrade for Supra owners seeking advanced motorsport features without the need to rewire the entire car.
Seamless Integration
The harness is designed for manual transmission models and supports the factory sequential turbo system (or single turbo conversion). It integrates with the factory dashboard and sensors while adding an auxiliary I/O connector for expansion. This allows for the addition of sensors like Wideband O2, Flex Fuel, and Fuel Pressure, which are critical for high-horsepower builds. The Nexus S3’s advanced logging and control strategies can then be fully utilized to tune the legendary 2JZ engine to its limit.
