Thought I had an old schematic but can't find it.... I think I can describe it to you. There should be 7 hook ups on the bottom of the valve. The 3 that run in a row are for your hydraulic lines from pump etc.The other 4 hook ups are for the loader cylinders, to hook those up looking down from the top( joystick side) of the valve:
Front right is for loader "drop"
front left is for loader "lift"
Back right is for bucket "curl"
Back left is for bucket "dump"
The 3 ports in a row should be marked with the letters N, P and T cast into the body of the valve...these stand for:
T = Tank port (return going back to the sump)
P = Pressure inlet from the pump
N = power beyond outlet to the Next valve
Your hydraulic line from the pump will hook up to the middle "P" port.
The "N' port will run on back to the 3 point hitch
The "T" port will dump back into your transmission
