Vacuum hosed outlets on my carb

[Scat Pack Fever]

Could someone please tell me what goes into these outlets? I know my brake booster and vacuum advance goes to a couple of those, but I'm not sure which ones. There are 3 in front and one that is "capped" in the back.

the pcv will hook to the larger one in the front,then the vacuum advance to one ,,the brake booster should hook into the intake directly not the carb,,and maybe one to your air breather,,and plug off any extras
