Completely redesigned and reinvented Toyota engine harness that fits perfectly and sports a stealthy look

In the initial mockup and R&D process the harness was completely re-designed and re-measured to fit perfectly along the motor. No wasted length on any of the sensor looms. The harness now routes underneath the intake manifold and each connector to its dedicated location. This makes for a great look, an easier install, an engine bay with less clutter, and much easier to work on when under the hood. Amphenol Mil Spec connectors are used at the Coil Packs and Boost Solenoid to keep options open for different setups. This means, if you’re running OEM Coil Packs and you get a Stand Alone and want to run our LS2 Coil Pack kit or any other coils, all you have to do is call us and we make a new sub-harness. Then you’d just un-plug the existing Coil Pack sub-harness, and plug the new sub-harness. It’s that easy.
