If you look in the picture below the red circle on the right there is a plug that looks IDENTICAL to the IAC plug circled on the left. Only difference is the color of the plugs, the IAC plug I am trying to determine where this plugs in exactly. Wasn't sure if the previous owner wired in a second IAC plug or what. He had wired in a second Alternator wire and gauge wiring for the drivers side as the alternator was installed on that side when I bought the car. I have since moved it back to the passenger side of the car. The car also had a small engine fire so he had got a second harness and tried to piece things together so the wiring is a tad on the WTF side. Just trying to figure out where this particular plug goes so I can get it hooked up or removed. Thanks in advance

 

That looks like the connector to tranny on driver side. (red circle right)

 

That is the Automatic transmission connector (700R4) should have three wires in it. Light blue, tan/black, and purple.
