Check out the prelude FAQ's man how to wire is in there, ok for your S model you need to wire.
1. vtec solenoid- ecu pin A4
2. vtec pressure switch-D6 and its ground- on thermo housing where ecu main ground is.
3. Iab's -Ecu pin A17 pink wire. Make sure you are getting 12volts from the yellow/black wire on the engine harness connector for the iabs
4. knock sensor-ecu pin D3
Are you re-using your f22a1 engine harness?

thanks a lot guys, i didnt mean to be like everyone else and not search the subject. i ran some quick searches but the search thing on this site sucks. i was a little pushed for time yesterday too, but thanks for all your help.

I always refer to the FAQs first because I've been told to search too many damn times. I could understand though, sometimes you just don't know which words exactly to search for and end up getting a ton of threads and usually being too lazy to scope out all of them. You'll eventually learn, I hope master the search function. Though it doesn't hurt to make a new thread every now and then.
