On a 87-93 stang?

The front has two coming from the center of the manifold, one to the corner tee fitting on the manifold were the pcv valve plugs to, and another one plugs to the long hose coming from the plastic fume canisters on the passanger frame rail.

The rear has 3, 4 if using speed density. On mass air the center one is capped off, on speed density it goes to the map sencer. The other three are on the long tree looking fitting, one goes to the red vac hose on the fuel regulater, one to the black hard plastic vac hose that runs to the passanger side, and the big one goes to the vacuume tree above the brake booster.

Its been a long time since I messed with one so I might be off.
