im swapping my intake manifold from an aebs to a b16a2 for smog reasons

there is a vaccum port on the top of the manifold...Where does the top vacum hose go to?

im not talking a out the one going to the pcv valve..theres an extra one on the very top

 

sorry i forgot to mention the intake manifold is from a 99 USDM CIVIC SI..im not sure if all b16a2's (if theres more than) have the same intake manifolds
