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 picture below. A
Bipolar Stepper Motor (ex. 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.
Step 1: Disconnect connector from IACV housing and gently remove the retainer
from the connector.
