Vacuum lines unconnected

While working at getting my '85 300D back on the road I found at least 3 vacuum lines that are not connected.

Any suggestions as to where they should go ?
It seems the black with red stripe should go into the open T but Im not certain.

One reason I was poking around is the motor doesnt shut off without the use of the under the hood stop switch.

The vacuum line to the 90 degree fitting on the vacuum switch is there, so from what Ive read that would indicate an ignition switch vacuum issue.

Ive done a vacuum check with a MityVac from the doors back and all works well there, doors, trunk and fuel door.

Thanks for any suggestions.

Is there a vacuum chart stuck under the hood somewhere?

I'd say the reddish one conects to greean dashpot for trans and ip shut off. The other goes on the other.If that does not help you reverse what I said.Some cars loose their vac routing paper.

A pic from a little further back might help. It almost looks like that 4 way split is missing. Also find out which one comes from the vacuum shut-off valve on the injection pump. There should be a dedicated line to and from the shut off valve on the ignition switch.

I don't know what the difference is, but when I click on those, they don'r get much bigger than the original thumbnails.
Still not seeing the 4 way connector, though, that might be what's supposed to tie these all together. Does one of them have vacuum when the engine is running? it would come from the brake booster hose more than likely.

There isnt a 4 way that I have seen yet. It just may be the 'missing link'.
I'll be getting into this as I finish the interior.

The dirtbag that stole the radio from the PO tweaked virtually every fitting and connector when he so nicely destroyed the console. Getting all properly together has been a PITA.
