Where does the hose go to that comes off the waterpipe?

and does anyone have a link to a diagram for all the iacv/fitv hoses?

im lost to where all the hoses go to

 

its on a 2000 integra LS

 

All coolant lines can be T'd onto another. Depending how your water pipe looks like. If your talking about the 3/4" outlet then it goes to your heater. But if you're referring to the 1/4" or so then it goes to your IACV.

 

i think he is talking about the one that goes to the IACV
