Some help with water lines

[Fiddle]

Hey guys hope you’re having a good weekend.

I’m in a bit of a confusing spot as I’m not too sure where to plumb my turbo water return line too. I have been told that it can be attached here. Pic1, where that red hose is attached. 

However, that red hose is routed up into something already. Pic 3 and was wondering where that would go. 

Also one last thing, where is that black outlet meant to be plumbed to?? Pic 2

thanks!!

red hose in pic 3 is meant to go over to turbo. Black thing in pic 2 is meant to have an air hose on it (running back into manifold I think?)
