Help with coolant hose routing on engine reinstall please

[providence]

stock m20 going back into my 91 325i.. PO had bypassed the throttle body, and I somewhat lost track of how the coolant hoses were routed during disassembly. I'm about a day away from getting this thing back on the road and could use some help breaking down how the stock hose routing goes. Bentley diagram is vague.. searching around on here hasn't turned up much.

The upper line from the heater core goes to ________
The lower line from the heater core goes to ________
The hose from the back of the cylinder head goes to ______
The fitting on the block goes to________
This weird inline valve is a ___________

etc. please help a brotha out.

either my car had some options package or was monkeyed with because I have T's spliced into the cooling lines and some kind of proportioning valve. I photoshopped this diagram with how I think things are routed but cant see on this diagram what connects to the back of the cyl head.

Ok all I'm really needing is what attaches to the lower heater line. anyone look under the hood for me?
