Other than the ball it looks complete. Is there something in the hole? It could be a turn over ball. If it is, then in the left rear wheel well there would be a "L" shape piece going through the frame rail. Pull on it and you should be able to pull the ball out and flip it over. Also the U-bolts can just pull up so you can hook the safety chains to.
There should be, I believe a 7-pin plug anywhere in the bed. It could be hanging there like mine is, or mounted to the side of the bed.
