Description

The FuelTech Universal 4 cylinder A harness is a great addition to any 4 cylinder build and can be used with both the FT450 and FT550 ECU’s in a complete plug and play style. It is to suit 4 injectors and 4 individual smart coils, wired in semi-sequential fuel injection and wasted spark ignition. It can be used with high or low impedance injectors; low impedance requiring the use of a peak and hold driver, high impedance requiring a peak and hold jumper harness (both sold separately). The harness is set up for either VR or Hall effect cam and crank sensors and includes 3 relays with built in fuses for main electronics, injectors and coils. The universal 4 cylinder A harness has a label for each connector and the insulation is heat, moisture and oil resistant.

TECHNICAL SPECIFICATIONS:

  • 4 EV1 injectors
  • 4 Smart coils
  • FuelTech Peak and Hold external drivers ready
  • FuelTech WB-Nano O2 ready
  • GM style intake air temperature sensor ready
  • GM style engine temperature sensor ready
  • 2 pressure sensors ready for fuel, oil / another 0-5V sensor
  • Extra output connector for generic use
  • Crank and CAM connectors (hall and VR options included)

This harness was designed for systems with up to 4 injectors, 4 smart coils and a FuelTech Wideband Nano O2 with Bosch LSU 4.2 sensor. It's setup to run semi-sequential or multipoint injection and wasted spark. It is already wired for FuelTech Peak and Hold drivers when using 4 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.

*This is only the A harness which is all the FT450 requires.
If you are using an FT550 and want to use all of the extra inputs & outputs, you will need to purchase the B expansion harness as well.

Can be easily modified to use different coils, injectors and sensors.
