You can always piggyback another 12v wire, or attach another wire into your fusebox (in the dash under the steering wheel [I would think it's still there, havent really looked at the 05 interior though]). That's how I wired the 12v for my gauges power.. you just need to look for one that comes on when you want it to, or else wire the switch in-line with that.

I dont know how many wires you'd want connected to one slot on the fuse box though, you'd want to talk to someone who knows more about electrical.
