Early IAC to Newer Design EFI Harness Adapter
Fuel Injection Harness
IAC Adapter
Older IAC has 2x2 like our 307016.
The idle air control allows the ECU system to control engine idle speed by controlling airflow around the throttle body blades.
This adapter connects an older IAC with a 2x2 weatherpack connection to a later model EFI harness that uses a metripack connection such as our EZ 2.0 or XFI Sportsman
