Take your pair of pliers, specifically non cutting pliers and clamp down on the metal ends of the wires and gently twist them until they are connected and thinner as seen in Photo 2.

With our holding screws primed, turn your pliers so that the wire makes a hook like shape as seen in Photo 3. Then tighten your holding screws again around each wire as indicated by the red circle.

As mentioned in Step 6, the direction the screw needs to be turned to tighten is away from you, so hook the wire into the bottom of the screw so that the tips are pointing towards you. See Photo 3 for the direction it should go.

For older wires like this, it is not necessary to connect a specific wire to ground or neutral, as in this case, older wires often did not have this, so they can be connected to either screw.
