We provide a wiring harness and computer to run a 5.7L or 6.1L Hemi in your brand new JK Wrangler. This harness/computer combination is designed to be a direct-install item. Plug in all the engine and transmission sensors, plug our harness into the factory firewall connector, mount the new computer and the wiring is done! All other parts of the vehicle continue to operate properly including all gauges, the ABS system, cruise control and stability control.
We use all new OEM connectors and OEM quality automotive wire.
We recommend using 5.7L & 6.1L Hemi LX Series engine for best fit.
The JK Hemi Conversion is a specialty application that requires a custom computer (part#: R-0000-JK) to operate properly.
When installation is complete, the vehicle will need to programmed with the PIN# for security and the JK VIN# before it will run. This can be performed at any Chrysler dealership.
We recommend upgrading your radiator for proper cooling of the larger engine.
* We have experienced staff providing technical support for all our harnesses.
