Touratech I think makes a dead simple GPS wiring kit for like $20, thats what I used for my 2720. Run wires from bars following the stock harness, attach and connect ring terminals, tuck fuse holder up by the airbox, done.
Bash3r, did you find the wiring kit? I've had a 60CSx for over two years and I love it. What's new is the WR250R and I am looking for a wiring kit myself.
Yea here's one that will connect it straight to the battery, I don't have this but skierd sent me the link. Or you could custom wire it with other accessories with the Beaver 3circuit jobber, this one is plug n play though.
