So I took out my old IAC valve in my car listed above LX VTEC and I put the new one in and I cannot remember where the three hoses go that come off of it I got the one that goes to the coolant line. I got the little small one that doesn't have a clip on it but the one that is longer I have no idea where that goes.

No worries, here are the instructions on how to reinstall the IAC valve. It looks like the two lower hose are for coolant, they will have clamps on them. The remaining hose must be for the air intake tube. Check out the images (below). Let us know if you need anything else.
