The plug is supposed to be there however the retainer is missing that holds the plug in. It goes over that spot and bolts in on both sides. Also, the hose is flat because that is not the hose for the car. It is obviously twisted to make it fit. I'm sure it serves the purpose, but it is a 1/2 ass mickey mouse job. Are you sure these are the only 2 things that caught your attention? At this point I would wonder what else may be mickey'ed. I would take a closer look if I were you.
