Here is another option for a log splitter or a BH.
1/2" NPT 20 GPM PRINCE SELECTOR VALVE
Use this valve to switch between the 3pt and the log splitter valve.
You would cut the line going to the 3pt and install the selector valve using compression fittings.
The PB line would go to the IN port on the valve.
The 3pt hose would go to one of the OUTPUTs of the selector valve.
The other OUTPUT port would go to the back with a QD on the end.
When you want 3pt, operate the valve to supply the 3pt.
When you want log splitter, operate the valve to supply the log splitter.
