hey fellas, 89 f150 EFI 302, i have two idle air ports on my throttle body. pulled the top end apart and labelled everything but as i was cleaning some stuff, what i wrote on the tape came off. now i have no idea what plugs into what. i have one hose still on the bottom port, on the TB, and the one port on the top is esposed. any ideas where the hose thats on the bottom one goes, and what hose plugs into top, exposed one?

 

Vacuum diagram is on the air box.

 

not on this poor old thing. lol im almost thinking that the owners before me just plugged the the top hose with the bottom one too. so it goes to nothing, i cant seem to find and nipples or extra hoses that is should plug to. all of my other hoses i have labelled go to something
