NOTE: The fuel pump relay used in the EZ-EFI® 2.0 fuel pump relay harness is a special solid state 

relay.  It is compatible with return style fuel systems and required for returnless style fuel systems.  Its 

wiring is different than standard relays.   

Ignition System Options 

The ignition system components that are needed and the wiring harness connections that will be used 

depend on the type of engine and whether or not the EZ-EFI® ignition timing control capability will be 

used.  In all cases, the EZ-EFI

®

 requires some form of input signal to tell it RPM.  If the EZ-EFI

®

 will 

be controlling timing, that input signal will have some specific requirements and the EZ-EFI

®

 will also 

interface with an external ignition that will drive the coil(s).
