4 speed safety switch - Help Needed

When it comes to electrical issues, outside of putting in a light bulb, I am totally screwed. Body work and mechanical I can usually do so I hope someone can help me with this and please as detailed as possible. Currently my car starts without needing to push in the clutch. So I need to replace the safety switch on the clutch pedal. There is no wire for the new switch to plug in and it appears some one bypassed the switch and I can not find any place for it to plug in. I can put the switch in but I need to know where the wire goes to and if I need to replace any wires and where they go to and what they attach to?
Thanks or looking
