Elite 2000/2500 Plug 'n' Play Adaptor Harness Kit to suit Toyota Supra JZA80 2JZ (non VVTi)

This plug 'n' play adaptor harness connects a Haltech Elite ECU to the factory loom without cutting a single wire. Plug 'n' Play replacement of the factory ECU for Toyota Supra JZA80 2JZ non VVTi with manual transmission only. One side plugs into the Haltech, the other carries factory connectors, and the conversion stays fully reversible.

Why It Matters

A wire-in conversion on a street car means days of labor and a permanently modified loom. This adaptor removes that risk: factory-quality connector fit, correct pinouts out of the box, and a clean path back to stock. The JZ responds to standalone control better than almost any inline six: sequential injection, proper coil-on-plug dwell control, and boost by gear turn a strong engine into a composed one.
