Hi guys,

Could you please help with my VSV EVAP vacuum line connections on Black top AE111 20V.
there are two ports. One goes to charcoal canister, the other goes to ITB.
On the Toyota service manual the ports are labeled E and F.

The service manual describe air flow is restricted between E and F when it is not energized.

My Question is which port connects to E or F. Or it doesn't matter. wondering if there is a proper direction of air flow between the ports.

Thank You for any help in advance.
