Using your wire strippers/pliers, gently crimp the plastic insulation on the wire. Do this several times around the wire to make sure that you can pull it off.

Because the wire is so thin, it can be easy to accidentally cut through the wire on this step. Take care to only cut through the insulation.

You will want to see a score line in the insulation all around the wire like this.

Pull the end of the insulation off, exposing the wire.
