This is a "plug and play" kit suitable for EVO6-9. Constructed by a qualified Auto Electrician. It connects to the Alternator output stud in the engine bay fuse box and passes through the firewall hole (grommet is included) above the accelerator pedal and plugs directly into the fuel tank harness under the carpet in the rear RH footwell. See additional photos. Detailed DIY instructions coming soon. If you have any questions about this product you can contact us on the Facebook page.
