Accufab has several optional accessories to help adapt an Accufab 5.0L Ford style throttle body to be used with GM electronics instead of Ford electronics. For example, we offer a TPS adapter to use your GM TPS (Throttle Position Sensor) or an IAC (Idle Air Control) adapter to use your GM IAC. If you need to relocate the IAC or block it off all together, we have developed parts to help accomplish these goals.

Accufab has developed a Idle Aif Control - IAC adapter that makes it possible to use a GM Early model year (THREADED) or Late model year (NON-THREADED OR SMOOTH) Idle Air Control Motor on an Accufab, Ford style throttle body. Polished, billet aluminum.

IMPORTANT: BEFORE ORDERING, PLEASE DOUBLE CHECK YOUR GM IDLE AIR CONTROL MOTOR TO SEE IF IT'S THREADED OR IF IT'S NON-THREADED, SMOOTH. 

GM Early Style IAC Adapter- Our part number IACGM-1 allows a GM early model year "threaded" style GM IAC motor to be mounted on an Accufab, Ford 5.0L style (65mm through 105mm) throttle body. Includes adapter & IAC gasket. (Your GM motor will actually have threads on it and screw into this adapter, have a square connector with 4 connector cavities and no other fasteners are needed)

GM Late Style IAC Adapter - Our part number IACGM-2 allows a GM late model year "smooth, non-threaded push-in" style flat 4-pin GM IAC motor to be mounted on an Accufab, Ford 5.0L style (65mm through 105mm) throttle body. Includes adapter & IAC gasket and two fasteners. (Your GM IAC motor doesn't screw in, it simply pushes into the adapter, and has flat 4-pin oval connector. After it's pushed in to the adapter, it's held in place with two small fasteners.)

Idle Air Control Motor is not included.

Note: Chrysler Flat 4-pin IAC Motor is different than the GM IAC motor, although it looks identical, the bolt pattern to fasten the IAC motor to the adapter differs and does not bolt on to our adapter. Accufab does not recommend modifying the adapter to work with a Chrysler IAC Motor. Forcing it to fit, will strip the threads on the adapter.
