Top left port A should should go to the base end of lift cyl, and lower left port B should go to rod side of same cyl. C port should go to base of curl cyl, and D port should go to rod end of same cyl.
I can't see any port letters.
Since the pressure comes in from the left, the first set of upper lower might go to the lift cyl. It is easy enough to test, Push forward on the FEL lever should lower the lift arms, and have float, and pulling back should raise the lift arms.
A left push on the lever should tilt the bucket up, and right push should dump, and if you have regen, cause a fast dump.
