I remove the cap. There are about 5 spokes inside the base. I twist a piece of drop ceiling wire onto one of the spokes.positioning it toward the outside edge of the base. I then screw the cap back on letting the wire hang outside the vent ( bending it down the side of the base so you can screw the cap on). Where the wire comes out I drill a small hole in the cap and then thread the wire through the cap and give it a couple twists. Cut the excess wire and you should be good to go
