The lines to the backhoe have to be connected together if not connected to the backhoe. Pressure relief is provided by the backhoe.
I once left the lines unconnected while disconnecting the backhoe. Started the B20 tractor to pull ahead and immediately deadheaded the tractor hydraulics and burst an unconnected line at idle. So thinking that supply line had no relief protection before the BH or 3pt lift valve. Maybe source of high pressure damage. That line also provides hydraulic flow looped to the 3pt lift.
Don’t know if your BX similar.
