Highboy power steering conversion question

I have a question as to which ps lines do i use off the old hydro assist ram. Im thinking that i use the 2 lines that go to the pump and the other to that go to the ram mounted on the axel are eliminated? Also, i attached a pic of the 78/79 box, can someone tell which lines go to what? Any help is appreciated. Thanks

I did not use any of the lines off the old system when I installed my 78' box into my 74'. Had to have a new one made for the pressure side and used fuel tubing on the return. If I recall correctly, the smaller line is the pressure one and the larger one is the return (seemed backwards to me, but that is how it worked).

The fitting on the left is high pressure and the right is return. Go to a hydraulic shop they should be able to make you a fitted hose for about $50.00.
