Wiring Specialities - JZ Series Wiring Harness (1JZ / 2JZ)

Built for the weekend racer who doesn't have time to piece together a harness from ten different vendors, this kit combines Link Engine Management with Wiring Specialties construction — assembled to the exact configuration Adam LZ runs and refines on track. No guesswork, no forum-diving for the right connector. Every sensor location, ignition setup, and boost control provision was locked in through direct feedback from real competition mileage, not a spec sheet guess.

Choose your engine harness, pair it with the sensor and electronics package you need, and build. No hours lost in menus — this kit ships ready to install.
