ZC vacuum

I just put a Dohc Zc in my hatch and wonder if someone can help me. :apoke: I have everything hooked up except the sensor(i think its the eacv) right next to the map sensor , I can't figure out where this hose go's. Also on the ZC intake manifold on the back there is two places for hose's, do I just T them and run it to the one sensor or what? Thanx for any help you can give me , will be posting pics this weekend.
