Here is a pic of mine installed in the fairing. There is ample room for the servo, my two horns, and all that extra wiring. It's impressive how much space is inside that fairing. You won't have problems routing the wires and vacuum lines, getting everything hooked up under the air box was much more of a PITA IMO.
I did this install a couple of years ago when Murph's first started selling the kits and did NOT use a vacuum canister. I have had no problems, all I did was tap into two of the intakes with check valves.
(I was changing horns and risers in this pic)
