Several years ago I installed and Audiovox electronic cruise control unit on the FJR that I had at that time. It worked great. The K1200GT that I just traded for the GS had cruise from the factory. I liked that too. The GS has a Wunderlich throttle lock that the previous owner installed, but I prefer a dynamic electronic unit that adjusts for inclines, headwinds, etc. I'm looking at a Rostra unit. All electronic, no vacuum supply needed. At about $250, it's a lot cheaper than the MC Cruise unit. So my question is, has anyone installed a similar device? Short of that, can anyone tell me where to look for the VSS wire and how many pulses per second it generates? I'm taking a trip out west this summer and would love to have the unit installed and operating by then.
