I saw a post somewhere on here where there is and unused accessories connector under the seat they used. If so l am going to see where its fused etc and possibly run a wire foward under the tank to split off to power charger, heated grips and gps.
I really like it - two USB ports @ 2amp (fast charge), blue lighted, dust cover.
Note that link is for the 7/8" bracket, not sure if it will fit the Valk 1" bar? I drilled a hole in the side panel and mounted it there instead.
There may be much better out there, just tossing in what I use and am very happy with.
