There will probably be several options for an electrical source to serve a new outlet. For instance, it is likely there are several suitable wall receptacles in any given room to extend the circuit to another room or another floor of the house.
Mark and cut a hole about 4 inches wide in the wall to expose the top plate and a few inches of the wall cavity. Also cut a few inches into the ceiling to allow for reaching in to grab the fish tape.
Place the hooks so they point in a clockwise direction and the insulation runs all the way up to the screw. Don’t leave any bare wire between the terminal and the insulation. Tighten the screws to clamp the wires down. Same goes for clamps that are tighten over a straight wire, there should be no bare copper showing.
Fit a nail guard into each notch, covering the new wires. Drive the plates down tightly making sure they are flush and not protruding from the stud surface.
