I'm not sure if there is a kit or anything to add factory cruise control, there may be aftermarket ones though. Basically for a cruise control system to work you'd need:
- Cruise Control Computer and controls
- Servo motor (for throttle control)
- Brake switch to disable system
- Clutch switch to disable system
- References from the PCM (Indicating vechile speed, etc.)
I'm sure it can be done, but it might not be worth the price.
