I recently put a set of
these on my Legend. I'm pretty happy with them... the tops of my hands still get cold on long/chilly rides, but no more numb/cramped fingers. I like it much better than big, bulky gloves...
The included switch is big and clunky - I replaced it with a 3-position mini-switch from Radio Shack, that I actually managed to mount inside my switchgear. With some careful drilling and cable routing, the extra wires aren't too obvious, although it's definitely not as clean as without the extra stuff.
BTW, if you connect the grips to the headlight wire, they will switch off when the ignition is off, so they won't drain your battery even if you forget and leave the grips on.
I found
these instructions quite helpful. It wasn't too difficult as long as you can solder, and puzzle out the wiring diagrams in the haynes manual. It was pretty time-consuming though.
I have photos... one of these days I'll post 'em :-D
HTH.
