Nice! I always find the symbols rather cryptic.
I installed a fusebox kit from Eastern Beaver, it included a relay and all wiring, which makes it easy. The 'key on' power signal for the relay I got from the rear tailight wire. Relay (small black box) fit nicely under the RH sidepanel.
The fusebox I placed in my round headlight bucket, where it has been very handy for adding electrical stuff. Power outlet for GPS, battery monitor, Vapor speedometer, heated grips, amber running light. Two outlets are power on all the time and six, controlled by the relay, are key on/off.
