There is a lot of room under the plastic surrounding the passenger grab rails, but it's behind you when you ride. There is not a lot of room behind the plastic by the knee, and that's a pretty nuisancy piece to get off even without adding plugs and wires to the mix. Outlets on top of the pocket covers, well, at least you are drilling something inexpensive. But then you have to route the wiring through the inside of the pocket. You could put an outlet on top of the tipover wing. You could put one on one of the faux speaker grills on the instrument surround but it would look weird there. In the end, I just ran the wire for my Gerbing jacket out between the seat and tank, with no fixed outlet. I put a cig lighter outlet in one of the fairing pockets to power GPS, and just shut the pocket lid over the GPS power cord as needed.
Oh, and another idea would be to get one of the low clearance powerlet outlets that actually sit on the outside like a lump. I have ended up putting those on several bikes.
