Installing 3rd function valve on Zetor 4320 with Series 102 FEL

[ddu-ddu-du]

I'm working on adding a grapple to a my Zetor 4320 that has the Series 102 front end loader. I'm asking my mechanic friend to do the works with me and he says we need to install a 3rd function valve. But I'm not sure where the hydraulic line should be connected. Should it come from the power beyond port, or is there another recommended spot on these tractors? If anyone has done this setup or has a diagram, I would appreciate some guidance. Thank you.

For the Zetor 4320 with Series 102 loader the 3rd function valve usually taps into the power beyond port, but its best to check your tractors manual or hydraulic schematic to be sure.
