Connect your FiTech fuel injection system to your Dakota Digital EFI Interface Module with this CAN bus adapter harness. Ideal for Full Size Jeep owners upgrading to aftermarket fuel injection and digital gauges, this harness allows your FiTech ECU to share engine information directly with your Dakota Digital instrument cluster.
Designed for compatible FiTech LS, TBI, and TCU systems, the harness connects your FiTech ECU, Dakota Digital EFI Interface Module, and FiTech handheld controller. Depending on your EFI system, available readings may include engine RPM, coolant temperature, intake temperature, air/fuel ratio, boost, vehicle speed, and transmission information.
IMPORTANT: This is the wiring harness only. The Dakota Digital EFI Interface Module and compatible digital instrument cluster are sold separately.
