Wiring the FAST EZ-EFI

Our Infinitybox wiring harness can be used to provide switch electrical power to just about anything in your car.  This post shows you what you need for wiring the FAST EZ-EFI system.

First, installing any fuel injection system is a process.  Familiarize yourself with the instructions for the EZ-EFI system.  You can download them at this link.

Wiring the EZ-EFI is pretty straight forward.  You are going to use the ignition output on your POWERCELL to supply the switched 12-volts for the EFI system.  The MASTERCELL and POWERCELL in your 20-circuit harness replace the need for the relays to control the fuel pump and the cooling fan.  Connect the wires in their harness per this diagram.

It is important that you install the diodes that are shown in the diagram.  Our recommendation is to use a 1N4001 diode.  You can purchase these easily on-line.  Please note that the orientation of the diode is important.
