I finished my CCS-100 installation today, and then took it for a test ride while the bike was still naked. I need to flush my hydraulic lines before I put all her Tupperware back on. The cruise control worked great at speeds below 40 MPH, and the switch assembly I fabricated and described above worked flawlessly. I'll try the cruise control at higher speeds after she's buttoned all back up.
In addition to the handlebar switch, I did a couple other things a little different. I fabricated a small white nylon "anti-snag" plate tie-wrapped to the front of the throttle bodies, and I anchored the CCS-100 cable bracket to a different bolt on the engine (see photos). Another cruise control thread spoke about trimming some of the rubber intake snorkel in order to gain clearance around the added cable. Me? I rerouted the (crankcase ventilation) breather hose to the interior of the airbox (again, photos attached).
I did include a vacumm canister in my installation, and used one which has a built-in check valve. The cruise control module was mounted where my left-side Honda dashboard speaker was located, and the canister replaced the right-side speaker. I'll probably list the OEM speakers and enclosures once I've finished cleaning up.
