engine coolant line routing - 08 600 HO

[knee deep in it]

I am replacing my 600 HO turbo with a 600 HO based 730 engine I am confused about the coolant lines

there are two lines coming from the front cooler. One loops into the bottle through hose 12. What does the other other one (hose 16) connect to? Hose 16 goes to where?

Hose 6 and 11 go to the two engine connections so I have one extra line and no logical place to connect it. Is there a TEE somewhere?

Appears to connect to the front cooler

Should connect underneath the thermostat, up between the reed flanges.
