I got the bike 2 dys ago, after only learning of them in early July when looking for a new ride. Got lucky and located one 1.5 hrs from my house at a dlr who ordered 1 that had gone unclaimed. Altho I was looking at AltRider and Caribou accessories dlr had ordered and installed all OEM farkles, 'as per the sales poster'. so I gladly took them, at a descent discount; Inclusing the grip heaters.
The control is mounted bet the L-side mirror and the handlebar. Control has 3 mount points(holes), they used the fwd hole. I can take a pict if it helps but as I just signed up it may take me a month of sundays to figure out how to post. ;o)
