Hose placement

So I am new to sti engines. My old motor seized. I had a tech that specialized in foreign cars replacing it. Stuff came up and he left me with it unfinished. I believe I have almost everything back together then I find a random hose under the intake that I can’t seem to place. Also the coolant lines off the throttle body. I can’t seem to figure out how those are run. Any help would be much appreciated.
