Cat 236B2 Pilot Joystick Assembly

I have a cat 236b2 that I am replacing the pilot gp valve. The old one that I took off was not hooked up properly or not the original. does anyone know how to determine which hose goes where on the joystick? I've found all the schematics to hook up to the pump but cannot find anything on how they hook up to joystick. It is part# 299-9119. Thanks
