I need some help with understanding where some vacuum lines go in my 1999 Porsche 996C4. I have looked at all the YouTube posts that I can find, the service manual and the supplier pictures but cannot find where they go. Any help would be appreciated.

The pictures identify the connector an vacuum lines.1 Not USED

You say that you looked up YouTube videos but I covered this exact question in my video. I promise not to take it personally.

Hope this helps:

5,6,7 are related to the intake x-over valve assemblies. (If you have PSE they also can be related there... )
Some of them look like they got drug out to the wrong side of the intake manifold, Whatever you do make sure you sort it
BEFORE you put the engine in. I left "one for later" and payed the price in busted knuckles and foul language to get it connected.
Luckily my daughter has tiny petite arms and is very sharp on putting stuff together and she could reach the connection.
