My new tank plan & How should i plumb my tank?

[Tarolisol]

Well i am soon to be ordering my new tank approx. 66"L 30"T 24"D this will be an inwall tank, but in the room where the tank will sit there will be a wall directly on one side of the tank and a support pole aganst the other side. Heres my plan return pump amp master 3000 hooked onto a ocean motions 4-way. So my question is how should i plumb my tank, as in how should the water enter back into my tank with my ocean motions 4-way. If i drill holes where should they be or if over the top where should i direct the water.
Thanks all for any suggestions.
