its pretty simple really, air in (inlet), which on efi will go to an induction kit etc

there will be a oil feed on the top

oil outlet pipe on the bottom

water inlet on top(if watercooled), water outlet underneath

small pipe from the actuator to bleedvalve etc

small pipe from compressor housing to bleedvalve etc

big pipe from the compressor to the intercooler

hope this helps, needs a diagram really
