The FAST EZ-EFI 2.0 main harness is the primary wiring harness included with EZ Fuel + Ignition kits and adapts to throttle body or multiport configurations. It supports multiple fuel pump arrangements—including in-tank and inline options—provides electronic fuel pressure measurement as standard, and integrates nitrous timing retard and AFR targeting for wet nitrous systems. The harness works with common ignition systems; precise control is achieved with a FAST distributor or crank trigger.
