I wired mine straight to the battery. If you buy the genuine Honda plugs then its a straight plug and play affair.
There is a power point under the seat you could use as well, but in the end I just put a wire straight through with a inline fuse. Might put a little on/off toggle switch in there somewhere still
Slight PITA though, as you have to remove the left side fairing if you want to mount it into that plug space in front
