Keep us posted Royse, I've never seen this aftermarket system before. I'd like to see how this works out.
Looks to me like this a single cylinder system. Leave the cylinder disconnected when you fire it up. That way you can see if you have going the right way.
Also, to bleed the air out, jack up the front end and move the steering wheel full and right and then full left a few times. That will get all the air out. At least that's the way the stock system works.
Good Luck!

Might I suggest some 90* port adapters to turn the hose runs straight down and to the sides.

Just curious, but how did you ultimately 'map' the ports?

That looks like a "Char-Lynn" power steering unit. They were used on John Deer, IH, and others. I have a friend that has one on an NAA. Uses only one cylinder, but works very well. joe

Excellent idea! I might have to add a nipple to the top one to space it out a little over the lower one, but it would look much cleaner and take some strain off the hoses.
Thanks!

Mapping them wasn't really an issue because it was mostly still assembled when I got it.
The top hose was connected to the high pressure side of the pump and
has a unique fitting that wouldn't connect anywhere else.
The lower hose has a low pressure barb fitting to go back to the resevoir.
The two side hoses were already connected to the cylinder that helps you
move the draglink. The fittings will only fit there, although they could be reversed.
I did end up hooking up my air hose to it so I could tell which of those two hoses were
pressurized when turning left or right.
I have left the cylinder loose from the draglink so I can find the "neutral" position
on the cylinder movement and then tighten it in place.
It is a first time project for me, so recommendations are welcome.

I think you're right Joe, although I haven't been able to find a name on it.
This one is also going on an NAA with a single cylinder just as you say.

Communications is sure difficult sometimes......all along I thought you were trying to figure out the hose position/connections, but now I think you were concerned about which end (mechanically) does the steering wheel connect to? Is that right? OK, so does it make a difference which end steering wheel connects to & if so, why? Realizing hoses could be swapped.

Hmmm, clear as mud. Sorry about the confusion. 
Yes that is correct.
Specifically I was wondering about the return line.
Mechanically I wouldn't think it would matter, but would it make any
difference if the return line is on top or bottom?

Possibly because it might be a torque amplifier and doesn't drive a cylinder. After counting hoses I discounted that idea

Don't think it is a 'torque amplifier' like the Charlynn on Farmalls, but rather just a control for the double acting cylinder attached to steering links/rods. On those Farmalls, there is no other cylinder, just the single device inserted inline with the steering wheel shaft.

Thank you both for your interest an help!
It is a control valve that drives one DA cylinder.
One pressure line, one return line, two directional lines to the cylinder.
I guess my question stemmed from wondering if gravity would empty the valve
if the return was on the bottom versus on the top, and what would happen if it did.
Hopefully I'll get it finished up this weekend so I can let you know how it works.
