I installed 2 power sockest on the lhs infil panel but on the upright part, 2 reasons for this, water wouldn't sit on them and they were used for satnav power and mobile phone power, easier to route cable to my satnav and tank bag, will post a pic at some point. I installed a 12V cig lighter socket, with waterproof cap, this is used to power a usb extension in the tank bag and also to power my airbed pump when camping, I also installed a dual USB socket, one works the satnav and one spare. Again, with a waterproof cap. I have it wired through a relay fitted in the tail so there is only power when the ignition is on, my heated grips are wired the same.
