Is your B set up for a BH like my BX? If not you will have to find the three lines, Power, Tank, and Power Beyond and use a valve assembly w/PB connection. Other wise nothing else will work when the rear remote is operating. If I do not maintain the PB circuit with the BH off, my 3 PT and FEL do not work. Get the Workshop Manual and you can trace out the hydraulic circuit, they are only $90. I am in the planning stages of building a large log splitter and will use the 3 BH line connection points for my splitter circuit, I will also have a log lift and hoist incorporated into it.
