This harness is designed for engines with up to 4 cylinders using sequential fuel injection and sequential ignition. It includes connectors for FuelTech SMART Ignition Coils, an integrated O2 sensor controller built into the FT470 ECU, and a connector for a Bosch LSU 4.2 wideband oxygen sensor.
The harness is also pre-wired for use with a FuelTech Peak and Hold Injector Driver. When using high-impedance fuel injectors, the Peak and Hold Injector Driver is not required. In this case, install the included Peak and Hold Jumper Harness, which is supplied with the wiring harness
