Motorhome 454 Swap question

[Smoky1978]

looking to get some assistance with identifying these vacuum ports I am unsure of. it's a quadrajet from a 454. number 5 there is a vacuum port under the fuel line. On the back side there is one vacuum port on the right not sure where it needs to go. The plug on the backside will go to my brake booster. appreciate your help.
1. I believe is to PCV valve.
2. ?
3. to charcoal canister?
4. ?
5.?

If you have sticker that came with engine, it'll have the hose routing on it.

If you look at that carb real hard you should find letters by the ports. Get me the letters and I may be able to help more. 1 is pcv 3 carbureator bowl vent,goes to charcoal cannister. The one in back goes to air cleaner. Get me the letters this is a PITA looking at your pic and trying to decide what letter it is. 2 if it's a T goes to cannister if it's an H it's for EGR. Please get me the letters. 4 vacuum advance the one under the fuel line is egr. Get me the letters just to make sure I got this right. I'm assuming you don't have all the thermo vacuum switches and vacuum delay valves etc. I simplified this a bunch figuring you aren't going to use everything.
