Locating a hole in the firewall for a vac line?

[Black-Hat]

Hello all, total noob question I've been having a good look and just can't see where I can run the vac line through the firewall can anybody stick up a picture pointing me in the right direction please.

Ive tried using the search function but only have access to the Internet via my phone at the moment so it's a pain!
I have an a3 1.8t AUM.
Thanks in advance for any help!

Eiether the grommet next to the pollen filter (passenger side) under the scuttle cover or drill a hole through the plastic cover where the cabling comes out (drivers side) under the wiper motor again under the scuttle cover...
