Hi I have a question how many vacuum lines do u have coming out of the firewall connecting to the vacuum resevior and going to the heater control valve Booz I have three vacuum lines coming out on my firewall on my 70 duster

This thread is about aftermarket units under the dash ( "knee knocker" ).
Those don't require vacuum lines.
Good luck to all
