TB pre wired for dimming mirror?

[ReefShark]

I asked this question earlier, but I did not get a reply. I bought a self dimming rear view mirror with compass and I plan to install it this weekend. I have heard that the 2002 TB LS has wiring in place under the headliner for the mirror. I did not get the temp in the mirror so I don't need to plug to a sensor.

Has anyone looked behind the headliner to confirm this? It is not a problem to wire as it will work with only positive and ground. There is a green wire that connects to the back up lights to prevent dimming when in reverse, but if not per-wired I can omit this luxury.
