4 speed safety switch

I am not sure how the safety switch is suppose to be conected. The car starts fine but I do not have to push the clutch which means it will start in gear. There is a wire coming off the switch on the clutch linkage from under the dash but it has been cut. I think it goes to the starter but sure the proper wiring to make it work. The way it is now is, batery cable to starter and wire from the starter to the relay. Can anyone tell me where it is suppose to conect to? Do I need to chage how it is wired?
