I should mention that my truck is a 2000 Chevy Silverado 5.3L with the stock cruise module. I tested the speed signal to the cruise, and it was a 12V square wave that was approximately 1 cycle per MPH.
The only wire cut is the speed wire from the PCM to the cruise module. I also tapped into the 'Set/Decel' , 'Resume/Accel', 'Cancel', and cruise power wires.
