The FuelTech FT450/FT550 6 Cylinder Universal A Harness was developed to be installed on 6 cylinder engines. This harness has all the components needed to make a plug and play installation on an engine with a standard setup. The insulation and connectors are moisture, heat and oil resistant.
The FuelTech FT450/FT550 6 Cylinder Universal A Harness is a plug and play wiring solution to be used with a FuelTech FT450/FT550 ECU. It has all the connectors, relays and fuses directly built-in and can be used with nearly any application with 6 injectors and 6 coils.

This harness was designed for systems with up to 6 injectors, 6 smart coils and a FuelTech Wideband Nano O2 with Bosch LSU 4.2 sensor.
Set up to run semi-sequential or multipoint injection and wasted spark.
It is already wired for FuelTech Peak and Hold drivers when using 6 low impedance injectors.
When using high impedance injectors, a Peak and Hold driver is not needed and in this case, only a bypass connector is required (jumper included).
There are 3 separate relays to power the whole system, separating the injectors and coils from the electronics.
To activate coils and injectors relays the Blue#6 output must be configured as Fuel pump or RPM activation.
