I am trying to figure out what these lines are for. And also want to make Sure they are attached at the right place.

I found this line, and metal U just laying on the driver side, going from a Black block next the wheel well. I don't think this is just a drain tube.



This line I am not sure about, but noticed it hanging down from what I think is the carbon canister, I brought it up, and attached to the place shown here. Just want to make sure this is attached at the right place.




This line comes from the original heater control valve (you can see the bulky replacement) where they had 2 lines coming from it. The line that I have going to nothing (stuck a small screw into it). Should it be plugged into something ? it is the line that goes off out of the picture.



Thanks for any help. I imagine that these are all some vaccum line, but unsure.

 

If that round black thing (last photo) is for the heater water valve, the hose on it would have to be hooked up to vacuum, specifically the part just above it that has the other vacuum hose going to it.

Two questions:
1) Does the heat control work?
2) Are you absolutely sure the mystery hose goes to it?

Because I think that hose may be the breather line for the automatic transmission.

 

First one is the breather hose for the transmission. Leave as is.


Second looks correct.
