Airbreather vacuum

Hi hope all is well in your world. Ok i've been tracing all my vacuum lines and i believe i have it right but it leave's me with nowhere to connect vacuum to my airbreather i need a connection on both sides on the drivers side there is an inside plate that needs vacuum to close i believe it probably needs to operate off a TVS heat operated vacuum the passenger side is heated off the heat riser tube but still needs some sort of vacuum does anyone have any idea's thanks.
