Supply ports to the auxiliary diverter valve when fitted. Used to send oil to a loader,spool valve or independant tipping valve etc.

Not supply ports. The only feed to the selector valve is from the stack pipe. Iirc they are both open galleries for return oil. 1 for oil being returned thro the R port of a selector valve. 1 to drain oil from the selector valve shock valve. Poke something down them. I'm sure they are open ports.

I want to mount an auxiliary distributor as in the video below I would like some tips.
Should the hydraulic pump be on continuous pumping?
I am interested in using it more to lower and lift the straps as in the video.
If I mount it I still do not understand the oil circuit to the cylinder. And when the straps are at full throttle, will the pump not come under pressure and will the protection system act? And also the oil that returns from the cylinder into the oil bath where it is made.
Maybe you can help me with these tips or any information is welcome.
I also mention that I want to mount it because I can not make the adjustments on the hydraulic side and I do not have the necessary tools.

Never seen a valve like that.
I'm guessing. The right hand lever is feeding the loader rams. They are single acting and it looks like one pipe from that slice goes to the rams and the other pipe ends with a q/r coupler which isn't connected to anything.
The left hand lever must be feeding the link arms cylinder as I can't see any external pipes.
He must have the quadrant in constant pumping and he will have protection from the internal relief valve.
