This FAST idle air control adapter converts a factory 5.0-liter throttle body IAC to be compatible with FAST EZ, EZ 2.0 or XFI systems. It’s intended for installations where the factory IAC needs to interface with FAST electronics, providing the necessary mechanical and electrical adaptation to integrate that 5.0-liter IAC with the aftermarket control harness.
