It appears correctly plumbed into the system. It looks like the pressure may be just the system flow pressure (but I wouldn’t have expected it to be that high unless the three point valve (or some other valve) is lifting something).
Did you actuate the valve to move the cylinder (normally attached to that port) in the proper direction to get pressure to build up on the gauge?

Assuming you are holding the valve full open yes.
Move the gauge to the boom spool and try agsin.
If that yields the same result disconnect the pump supply hose coming to the valve and connect the gauge to the end of the hose. You will need to replace the coupler on your gauge with a JIC-08 male fitting.
Once the gauge is connected start the tractor, read and record pressure, and shut the engine off. Do not run the engine any longer than it takes to read and recorx pressure. Remove gauge and reconnect the hose.

Try it on the other spool.
The curl port can lie to you on pressure because of regen.
