Undo each end of the plug wire, one at a time and one lead to one end and the other lead to the other end.

Ok so for example i would do between the cap and the beginning of the plug wire. Then i would do both ends of the wire. And then i would do to the end of the wire to the spark plug. Correct? Just trying to make sure im understanding lol
