LA463 loader valve question

[wickedinhere]

I was wondering if someone could tell me which port was the power beyond port
on the loader valve for the la463. One port is marked P and the second port is marked BY and the 3rd port is not marked. I am trying to hook up a wr long valve kit and the loader and tractor books dont tell which is which.

The markings indicate that the "P" port is the pressure inlet, the "BY" port is the power beyond and the other port is the return to tank port.

Here is a picture of it. It's that 90deg fitting.
