Cruise Control not working on a 1983 280zx datsun
 

I have thought about this problem for awhile and im not sure how to exactly fix it. I know that the clutch plug in ( where you can unplug something so that you dont have to have the clutch put in to crank the car) is pluged in. I was just woundering if i needed to get a little plastic peice that would be the stopper type thing that would push the button in to engage it.
