Once you plumb the first one in, it's pretty easy understanding the path the fluid needs to take. I took the outlet from the power beyond port on the loader valve (Kubota marks it as "BY") and ran that to the inlet of the new valve.
The new valve must have either power beyond capability built in, or a power beyond adapter (which is what mine has) added to it to transfer fluid to the next valve in line (the 3ph in my case). The power beyond port on the new valve feeds down to the adapter plate under the right floorboard, into the same fitting that the power beyond hose from the loader valve used to feed into. This places the new valve in series with the loader valve and 3 ph valve.
Tee-ing in (parallel connection) on the high pressure side of the circuit won't work since the fluid will take the path of least resistance.
The two work ports on the valve go back to the quick connects on the ROPS, and finally the "return" or "drain" connection is tee-ed into the sump connection from the loader valve, again on the adapter plate under the right floorboard. There's no problem using a T connection on the drain side since there is little or no pressure here, the work has already been done by any fluid at this point in the circuit, it's just going back to the sump.
I used 3/8 hoses, since that was what the tractor had in the first place, the Prince valve is rated for 15 gpm, I think the tractor puts out something like 9.5 gpm.
