OK....I had trouble finding the damned thing. Gotta remove the drivers side kick panel, as others have suggested. Go to back corner of the floorboard where the side panel and the firewall floorboard meet. Grab the thickest part of the wiring harness and follow it up. In the back, behind the wiring, you'll find a white plug semi wrapped in black electrical tape.
The plug is white in color and has a white adapter cover plugged into it. I cut off the electrical tape, and tossed the plug.
I'll post pics if anyone is interested. I'm guessing its 10 inches from the floor board. Don't remove the bottom dash piece (as I did) looking for the damned thing!
