We will integrate to your chassis the same way we always do, via our chassis specific adapters. If you do not see your chassis in the list please email us, or select one of our standalone solutions like our PDM system or our Race/Relay fuse box.
This harness is made to run through the firewall and into the cabin on the passenger side of the vehicle. We recommend mounting the computer on the cabin area near the passengers feet. We originally designed a fuse box style option that would kept the factory engine harness many years ago, but have decided a full harness was the only way to go. It was critical to get the engine computer and fuse boxes out of the engine bay, away from the heat, de-cluttering the engine compartment.
