I have posted before I have a L785 that had auxiliary hydraulics at one time but the main control valve has been replaced and the power beyond plug to the auxiliary control valve is not present. I have had no luck in locating a power beyond plug or finding anyone willing or able to make one for me. Would putting a "T" from the main control valve to the auxiliary control valve be a workable option? In my mind it seems like it would work but then I also think if it's that easy why didn't the factory do that and then there would be no need for the power beyond plug. Anybody know? Would the "T" need to be on the inlet or return side of the main control valve? Thanks - Justin

A tee will not work, especially on the inlet side. Oil will flow to the least resistance so the oil will just flow to the return. Blocking off the return will blow the hyd pump.
