I assume when you say control cable, you are referring to the shift cable? The shift cable connects to the mechanism near the engine crankshaft. If you remove the blade and the adapter, you will see the yolk with an eyelet hole where it connects. By moving the shift lever control, it "pinches" the belt at the crankshaft and using the technology like a snowmobile clutch, it changes the speed ratios. I hope that helps.
