2 vacuum lines not sure where they go.

Hi Guys,
I need some help. 2006 e53 3.0L I did the CCV fix, I did not take off the intake manifold I did it ( i guess) the hard way. Any how I'm putting the system all back together again and I don't know where 2 vacuum lines connect too.

1.) the Vacuum line that is next to the oil dipstack: ( UPDATE- THIS FIRST one seems to be a vent line from the transfer case.)

2.) This Vacuum line seems to be attached to the transaxle

Any help you guys can provide me would save the day!
I've looked on realoem.com and can't find a picture that shows the vacuum lines. If someone can point me to a shop manual for download or post a PDF that shows where they go that would be awesome.
Thanks in advance,

Yes both of them appear to be transmission vents.
Thanks for the replies everyone. Hopefully the next dude will be able to find this post useful.

The one by the alternator is for the front differential. The one back by the dipstick is for the tranny I believe.
