5.6L M117 air intake vacuum connections missing

[Solid Snake]

Hey guys,

Still in the appraisal period of what rubber needs to be acquired and replaced, and I figure I'm going to replace every little piece, including the air intake gaskets. Of course, I will take photographs every step of the way.

This is no exception. I found a few things while tracing lines that caught my eye, as to wondering what they may be, and also found one connection outright not connected. Attached are pics of my findings.



This sucker (literally) is unattached near the distributor cap. Any clue where it goes to? Following it back, it comes from here (driver's side valve cover):



Also, what are these?

This one has 3 connections, with one going into the fender.


And this one:




Sorry for asking so many questions; I just wanna know what these are and make sure I do it right the first time!

Thanks,

Carlen


(Also, how many rubber elbows and connectors should I get?? it looks like there are 10-20 of them!)
