Getting closer to dropping my sr20 into the car but because I bought it with a bunch of missing things I've been trying my best to research where things go and what things are. Right now I'm stuck at things under the intake manifold.

These are under the intake manifold and I know they are coolant lines, but where do they go? I know the throttle body has a "defroster" at the bottom of it, and I was just wondering if there are it.

Second part I'm wondering about is the IACV. I know the port facing the front of the engine is for the intercooler piping, but I have 2 vacuum lines on the back of the IACV that I have no idea where they go.

When the whole manifold is on the motor the 2 vacuum lines come out towards the back. Haven't seen anything on them and just wondering if anyone knew.

Both of those ports connect to the iacv.

So the things you pictured, all connect to one another. Not too sure orientation, though

The ports on the iacv are coolant lines and connect to the coolant ports you have circled in the 1st pic, the manifold sits close those lines are short, to long and they will kink.
