Does your BH use 3 hoses or 2? Either way the main hookup is the same, I'm working off my phone so editing pictures is a bit of a pain.
First you need to remove the metal power beyond line that comes off the loader valve and and provides fluid to the 3pt.
The red circle is the loader valve side banjo fitting.

The 3pt side of the line is circles in red in the following pic, note it'll be a gray steel line, not the flex line showed in the pic.

The replacment for the loader valve side fitting is a -6jic to #8 SAE 90* fitting,
The 3pt side will need a 3/8 BSPP to -6jic, either std length or extended will work, I used a std length but an extended would fit better but the right size isn't carried by any suppliers by me at the moment.
You will have to determine what length hose will work best bit I would recommend using flat face quick couplers for connecting to the BH.
Recommend 3/8 hoses with -6jic on one end and 3/8 nptm on the other.
You will connect the hose coming out of the loader valve to the IN or pressure side of the BH valve, the OUT/return or power beyond (depending on how your valve is configured) will go from the BH valve to the 3pt.
If you have a 3rd hose for a return to tank, that will "T" into the hose shown with the blue arrow in the first picture.
That can either be cut and have a 5/16 t connected to it or take the fitting out of the trans case and thread a fitting "T" with 2 barbs and a threaded fitting on the 3rd side, I don't have the thread size for the trans case, either method will work.

The second picture, where the the power beyond from the loader valve goes to the 3pt, is of the hose after I had removed the factory steel line, I didn't have any pre pictures.
When I get home I'll try to remember to look at the old steel line and verify that it's the same but I doubt Kubota changed it.
The loader valve side connection is SAE-8, I used a SAE-8 to JIC-6 90* adaptor.
The banjo fittings are eliminated with the new adaptors.
Did you have a chance to look at the original steel line ? I'm pulling a trigger and will pick up the BH65 on Friday, so I need to now sort out the hydraulics. One more question: Which way does the BH65 have the Quick Disconnect (QD) connectors, is the male on the input (line from the loader PB) and female on the output (return to 3pt) or vice versa ? I saw that my local Tractor Supply carries QD adapters, will generic ones work ?
Line out of loader valve to BH pressure in, BH return (out) goes to the transmission /3pt (the smaller fitting).
Yes the lines will need to be connected together when the BH is off and make sure to leave the 3pt lever in the down position when the BH is attached.
