I don't know where they draw their power from unfortunatly....I'm broke so i didn't go to the dealer to get it done....I took a deep breath and did it myself.
U might know more about the wiring than i do SCS.....I can only tell u what i did.....i tapped into the cubby hole light wires. Yes, the light behind the cig lighter, in that storage area. The only reason that i tapped in there, is because i wanted it to light up with the Headlights.
If u take that center console off, it's mounted in with a plastic clip.....I spliced the wires and connected them to my LED's....I have them in the center and side vents....and I have to say, NO PROBLEMs what so ever.
