Air cleaner problem. I NEED HELP!!!

Ok I have a 1999 ford windstar. I just put the motor back together and I have a hose coming off the air cleaner and I can't remember where it hooks up to. If any one knows where it would possibly go please please let me know asap. thanks

I know the hose you are speaking of. Without looking, I believe it hooks up to the spacer (that middle part) of the air intake manifold ... on the rearward (RH) side.
