I found it on the passenger side fuel rail under the black intake manifold. You can see it if you are standing in front of the engine.

it is mounted on the rear fuel rail toward the front of the engine ( passenger side ) it has two small bolts securing it to the rail and a four wire electrical plug and one vacuum line, this item is usually black plastic.
