The FAST early-IAC adapter converts an older two-by-two weatherpack IAC connector to a later-style Metripack/LS connection used by EZ 2.0 and XFI Sportsman harnesses. This adapter simplifies using legacy idle air control valves with modern EFI wiring looms, making retrofits and harness upgrades more straightforward for engine conversions.
