Hello,

Yes, the wiring diagrams show three wires to the IAC motor. Here are the wiring diagrams which are included in the engine wiring. I also included a guide to help you test the connections as well.

Please check out the images below and let me know if you need anything else.

Hi,

I tried finding a pic that showed specifics but was unable. So, I had to do it this way.

If you look at pic 1, the schematic indicates the wire color and pin it goes to. Pic 2 is the connector view. I numbered the connectors.

Let me know if this helps or if you have other questions.

Take care,

joe

See pics below.
