First Gen 4Runner Vacuum Line Help

First off I'm fairly new hear so any help is appreciated! My problem is I have a 1987 4Runner and its been through about 3 different owners and definitely isn't in the prettiest shape I'm trying to figure out the vacuum lines because the engine bay is just a mess everything looks about right except for that 3 port fitting that's mounted on the back of the EFI casing one of my lines has a drill bit jammed in the end(by one of the previous owners) and I'm pretty sure it's not supposed to be there. To preface this it does start but we don't have it idling yet fuel pump needed replaced and I'm finishing that tomorrow so I'll update on that status. Where exactly should each port on that fitting go to?

Mine is an '88 and only uses two of the three, one has a rubber cap on it. Probably just a dull junk drill bit with goop on it to replace that cap. You can get a box of caps from an auto parts store to make it look cleaner.

I strongly suggest you get the factory service manual from ebay or amazon or a digital copy from somewhere. It will help you more than you imagine.
