axle, gear an tranny box extended breathers

fitted my snorkel an now it's time to do the breather pipes
done both axle's then came to the tranny an gear boxs
but i'm not sure where the pipes should go
i had a look an found 2 plastic pipe's but are unsure what they connect to,
1 seems to go to the turbo hose but thats just one,
am i better to take the cover off the tranny tunnel to see whats what or can someone help me?

it's a 300tdi disco

thanks

Nick
