Hi, I'd like to know if you guys could let me know what these three openings on my throttle body are, and where they go to. Thank you!

big bottom one is the gas circulation that goes to the valve cover,

smallest one is vaccuum hose, the other i forget but if you gave me a pic of your engine bay i could point out what plugs onto it.

Isn't the little one the fuel pressure regulator line, the bottom one goes to the intake bellows and the medium one goes to the charcoal canister.
