Gregte:
I have done a short 10 mile drive with the SGII unplugged, and had no problems with the cruise control. I am hoping to get out for a drive today to play with it more. If not today, I will be making a 70 mile drive tomorrow on the thru-way.

Yes, the Rostra CC plugs into the VSS to get the vehicle speed. It also taps into the tach wire as well.
Here is the install manual on Rostra site:

What do other cruise controls do to get the vehicle speed?
