IMPORTANT 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 instructions below. A Bipolar Stepper Motor (e.g., GM)
will have a 4-pin connector and DOES NOT need to be modified. This example is shown on a Toyota
Supra but the same procedure is required for all 6-pin Unipolar Stepper Motor Idle Air Control Valves.
*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 the AEM Infinity ECU.
