L-jet vacuum diagram?

[teahead]

I'm taking off this E12 induction to be used on the E9 and want to keep track of everything while I do it.


There's this one vacuum hose that's plugged. Any idea where it supposed to go?

Sure its not a heater hose?

Can you get a couple more pics? Like the source of the pipe? Sim is prob right tho. The corrosion on the plug seems coolant based.
