I needed a USB charging port for my phone so I installed one of these under the front cover.

For some reason I couldn't find a good ground or a switched positive up there so I had to run both a positive and negative lead directly to the battery by fishing them through the plastic body using a piece of wire. I mounted one of the USB female sockets above the left hand pocket in front of the riders knee where there is a rectangular rubber plug. Also added a weather proof toggle switch next to the plug and a 5 amp fuse next to the battery.
