Idle Air Control Valve Requirements
Many Toyota, Mitsubishi, and other vehicles use an Idle Air Control Valve with a Unipolar Stepper
Motor (6-pin connector) and MUST be modified. See picture below. A Bipolar Stepper Motor
(e.g., GM) will have a 4-pin connector and DOES NOT need to be modified. *This info does not
apply to vehicles that utilize IACV solenoids.
The 2 center pins (Black-Red wires) supply 12V power to the stepper motor in the factory setup,
however these pins MUST BE DISCONNECTED before powering on the AEM Infinity ECU.
