Adding Rear Hyd to a JD 820

[Wayne County Hose]

I'm doing a favor for a friend here. For the tractor in the pics below, I need to add rear hydraulics to work a manure spreader and some haying equipment. I'm told there used to be a FEL on this machine. That's where the valve came from. He wants to work his equipment from this valve. Am I right in assuming that the pressure line would be from the qd underneath the floorboard? If so, is that where I should hook the return to? I'm guessing that the hydraulics from this line does power the 3 point hitch also. And, in the third pic, there is a steel line going to a qd. What would that be for? Any help would be appreciated.
Thanks, Andy.

here are my guesses, this info based off of working on my dads old MF Industrial 35, therefor it may or may not be valid for a JD.

Am I right in assuming that the pressure line would be from the qd underneath the floorboard?

I would assume the same

If so, is that where I should hook the return to?

dunno, where does the pump draw from???
also what does the steel line above the QD do??? looks too small to be a intake for the pump, it is for power brakes???

And, in the third pic, there is a steel line going to a qd. What would that be for?

if it is like my dads MF-35, that is a line to run a single acting hyd cylinder, his has a 4 gpm pump in the tranny and there is a kit to let you switch from using that pump for the 3pt to using it for a single acting hyd cylinder, I would not bother with messing with it, other than removing that line and capping it off before it gets ripped off or springs a leak.
