EZ-EFI® Multiport Retro-Fit Kit Is Offered To Bring All The Benefits Of FAST’s™ Award Winning EZ-EFI® System To Existing Factory Or Aftermarket Equipped Multi-Port Fuel Injected Engine – Including GM’s TPI Engines, Fords 5.0L Engines, & Others 

The wiring harness is completely pre-wired and labeled for a simple installation.  It includes connectors for early style GM sensors (coolant temp, air temp, TPS, MAP and IAC) such as those found on a GM Tuned Port engine.  All of these sensors are available from FAST™ individually or in kit form.  FAST™ also offers a Ford style TPS that is directly compatible with the harness.  Or the harness can be modified to accept any 0-5V TPS.  The rest of the sensors need to be GM style parts. Wiring adapters are available from FAST™ to accommodate a later style GM TPS (round, 3 pin connector) or IAC (in-line, 4 pin connector).  Also available are a remote mounted IAC kit and an adapter for installing an early GM IAC on a Ford throttle body.  

The harness is wired for eight traditional “Minitimer” style injectors.  Injector adapters or connector kits are available from FAST™ to adapt the harness to newer “USCAR” style injectors.  The EZ-EFI® system must be used with high impedance injectors.  A wide range of high impedance injectors are available from FAST™.

The EZ-EFI® system must be used with a vacuum referenced fuel pressure regulator.  Returnless fuel systems can not be used.  FAST™ offers an adjustable regulator that is ideally suited for use with EZ-EFI®.  Various fuel system kits are also available.
