Re Massey Ferguson tractor and baler

Hi I have a Massey Ferguson 165 tractor and a 124 baler, does anyone know how I would hook up the pressure feed line to the baler, the baler already has the pipes going to the tensioner at the back on the side of the gearbox on the 165 tractor do I take bung plug out and put a hydraulic hose from there to connector on baler, or do I just forget about it and use the manual tensioner, thank you
