L322 PCV question please

can anyone help me please. (2004 RR 4.4 v8)
if you look at the image with the 2 ports that have the yellow locking rings. where does the small hose ( the on in top right corner with the arrow on ) go to as mine seems to be missing which might be adding to all my woes.

i appreciate your time and help as always.
cheers

To be honest, I don't know.....I do know mine has it from when I did my PCV a while back....

Looking at the photos I took, it comes over the top of the manifold into a small black/white filter, then into a black/white pipe and disappears under the drivers side electrical box....I believe there is a valve or vacuum sensor in there for the Secondary Air System....

Unfortunately I don't have my L322 with me today as the girlfriend has it....else I'd check!

from memory i don't have one either, i think mine is blanked of though as i dont have secondary air thingy stuff, there is a photo on one of my posts somewhere, i'll have a look tomorrow.
in fact i think both of the yellow connections on mine are blanked off, there is a couple of screen shots of a video i made to see what was going on with my pcv.
left and right ones below. mine is a 2004 v8
