I definitely don't want a free power plug under the seat - believe me, with all the stuff I store in there (tool kit, electric pump, tire repair kit, helmet cables, zip ties, space blanket, headlamp, manual) plus the space now occupied by the two new fuseboxes, there ain't any room for something like that to fit nicely. Besides, I'm anal. ;-)
jrw600 - I like it. I've played with drilling out a socket hole on the extreme forward end of the side tank panel, about 2" above where your socket is mounted. I like location, but I can't quite tell if there will be enough space behind the panel to make it work. At least the panel is cheap and easy to replace if I need to ... ;-) How is your socket mounted? Is that a bracket that is held by the hex bolt that holds the forward end of the side tank panel?
