Just finally getting around to getting the box plumbed and wired that we put on a Mack we bought. Question is, how do I plumb it to the pump? Not sure of the exact pump off hand, but it only has two hoses on it, one comes from the hydraulic tank to the pump, then one from the pump out. Our other truck has three hoses to the pump, so this is a little different. I'm assuming there will need to be a way for the oil to flow back to the tank when the pump is running and the box isn't going up? Would like to put controls to the rear of the box, how have you guys done that? This project, like most things I do is running behind schedule!
