7M-GE '86 Hose Connection Problem

[pasupra]

Hi everyone,
I've been working on my '86 Supra lately, I had to change the head gasket and now I'm pretty much done, expect I'm unsure about some of the last hose connections.

Problem #1:
The hoses running along the back of the engine bay. I'm unsure which hose to connect to the bottom end of the little T-PIECE.




Problem #2:
The valve under the intake plenum on the right of the engine. There is a round-looking valve and I don't know which hose connects to it.



If anyone could please let me know.
Where can I find them and where do they come from?


Thanks
-Pascal
