It is located on the left side of the engine mounted on the valve cover. Here is a picture. I hope it is big enough for you to see. It is number 18 on the picture. It unbolts and isn't that difficult to replace. Also, the only V6 that has the runner control is the 3.0L 4V.

Let me know if this helps.
