Sorry, I just noticed that you changed the vacuum sw on the brake pedal.
That only leaves the stalk assembly and the digi dash; are you sure the digi dash is for a cruize control car??

What year is the car? Is it a 6 speed or auto?
On the 6 speed there is a kill switch on both the clutch pedal and the brake pedal, as well as a vacuum dump on the brake pedal. With either of the kill switches reading the pedal down you get no light.
The procedure in the shop manual has you going to the passenger side of the dash to access the back of the cruise module to read voltage on pins. There was tech tip in Corvette Fever this month that tells you what pins to read voltage directly on the pins of the kill switches beneath the driver side of the dash. Either procedure is a bitch to get into the area of the dash where you need to read the pins.
I had to go through this on my 94 6 speed after a clutch master cylinder replacement. That's how I know a misadjusted kill switch will make the whole function just plain dead.

Buy the electrical diagnosis service manual supplement from GM for your year vette. This manual has a diagnostic procedure for the cruise control, a schematic diagram, and a description of the location of the components of the cruise control. Its tons cheaper than replacing parts and hoping your cruise control will then work!
