You may have to search under the center console to find it.
It should be there though.

It took me almost an hour to find it there. It was under the carpet, pushed down in a hole and wrapped in a black Velcro king of wrapping thing.

Getting to it after I found it was a quite the experience as well.

But in the end it was worth the effort. A little time searching and little problem getting to the cable sure beat running that long cable from the back of the car and all that would have gone with that project.
