On a cruise control equipped one there will be two separate switches on the clutch. The one that is there now, keeps the car from starting unless the clutch is fully depressed.

The definite test to verify if your car can have OEM cruise control is to check the voltage on the ECM pin 40 of connector A21 (my DIY shows the detailed location of that pin). If there is 12 V on that pin with the ignition in the ON position then the ECM supports cruise control. If you do not see 12 V on that pin, then it does not.
