The ones that I have seen, have connector plugs on the ends of the units. Kinda scarey in my mind. These were some sort of a 4 wire flat(If my memory serves me correct) plugs. There was one for each cable that jumped. They were located on each end. There was a notch cut in the sheating on the outside. Once set up then they sided over it. only way to access it later is to remove siding. (great!)
It too had all of the big appliances on the side with the panel. Only lighting and general-use recepts. on the opposite side.
