That 'drill shaped pin' should be in the spark plug cap Look in there and you should see it. If it is, just press and turn and it should grab the wire and make contact. You may need to trip 1/4" off the wire if it's frazzled. If you see the pin has broken off in the end of the wire just go to your local moto shop and get a new cap, NGK and lots of other companies make them. Cut the wire for a clean end and twist the new cap on.
