Chester,
Disengaging the cruise should not be affected by the LED ground (or lack thereof). The cruise should be disengaged by 12v from the brake lights when they are on, the same applies if you have a clutch. A hot wire supplies 12v to the brake light/clutch switch and when the pedals are pressed down the switch closes and completes the circuit. Your brake disengagement circuit on the cruise control should get 12v when the pedal is pressed and 0v when the pedal is up. I'd check the integrity of that circuit first.
