S-197 gurus, I need a wiring diagram for an 07 GT map light
 

I'm hardwiring my radar detector and need to find a good 12v source located near or at my map light. I found a ligit ground there, but am having difficulties finding a nice 12v. I know that the 05/06 wiring is most likely different since most people are finding that the black/dark blue stripe wire is providing power (not in my case though).


Thanks for the help,
Brandon
