I get more confused the more I read lol...
I found the image below:

While waiting for responses to the thread, I took the passenger side intake "boot" thing out. Under it, on passenger side, I saw what appears to be "H" in that image, but there's nothing connected to the black side of it!
EDIT: some more googling. seems that black and white valve thing connects directly to the intake boot. Maybe it fell out when I removed that tube from the intake. So now just trying to see where the other end of that 4-way connector hose goes (preferably without removing manifold lol)
Getting a bit.. overwhelmed now... supposed to be a quick AOS swap... now this. Note there's no codes thrown related to SAI or anything. Only 1128 and 1130 when the AOS went.
I can't even "trace" where that 2" line would go to since it's not connected to anything. I REALLY don't want to remove the passenger side intake. Is there something under it though that this connects to?
