Can someone please ! I can't figure out where these lines go? Here are a few pics of the lines I'm talking about.

PVC tube assembly, where does the top left end go?



EGR system? Where does the hose elbow with the red and brown wire go?

Booster, does the lower right hose on the trottle body go to the brake booster?

I've been working on my truck on and off for the last 4 months and have forgotten where these items go (had to do some head work.) Everything else I think I have down?

Thanks.

 

To the lower part of throttle body. That line goes to the fitting that carries coolant to the throttle body elbow on the passenger side.
Where does this end go That line goes to the rear of the throttle body elbow. There is a rubber reducer that it fits into.
