new hydraulic steering question

I am building my own hydraulic steering system for my 300U. Patterned after Jackson Power Steering kits. I have the steering motor and cylinders all mounted and plumbed. Now the question. Where can I tie into the existing hydraulics to get pressure? I have no loader and just the valve for rear lift. In front of lift valve there is a plug on the body under the right edge of the seat. Looks like it is for a 2nd valve assembly? Any and all help is greatly appreciated
 
You will need either a separate belt driven pump, or to use the existing system, you will need a "priority flow divider valve". To use the PFDV, which is the most common and easiest way to go, you would plumb it in the pressure line coming out of the pump, with the "priority out" going to the steering and "secondary out" to the existing system. What this does is assure that even when idled down, you do not loose your power steering. It can however rob enough flow from the rest of the system that when idled down, your 3 point or fast hitch will operate slow, or not at all. My 240U will loose flow to the 3 point unless I am at about 1/3 throttle or higher.
I have seen PFDVs at TSC and you will need one sized to your system with probably about 3.5 - 5 gpm to the priority port.
