help with holley 2 bbl vacuum hoses

thanks Dan,this is what I needed. What does #5 do. just plug it. also, which one goes to the vacuum ball that mounts to the fender on the pass side. That ball controls the heater box doesnt it. My son has a 73 Dart Sport with a 360. automatic tranny. No emissions. this engine came out of a 79 Dodge RV. I removed the charcoal canister. but am going to put the vacuum ball back on the fender. which port do I use for that.I am prolly going to leave off the PCV valve because I am running M/T valve covers and the hole is too big for a grommet. Is this ok. thanks again.
