1985 300D Vacuum issues Help

This morning I was changing the steering gear box, and in the mean time I unplugged a bunch of the vacuum lines that are right above the gear box. I hooked up most of them but there are a couple that I am not sure how to hook up. I was wondering that if someone could take a photo is they have the same model so that I could rearrange everything the right way.

The car also does not shut off as well. I havent tried to drive it yet so not sure how the transmission will shift either.

^ I understand why it doesn't want to shut off, there is an open "distributor" on the line that goes to a four way which goes to a check valve, a green line and a brown line, this is allowing a leak where there shouldn't be one.
That is an unusual set up, but 85's are a bit different.
The attachment is from someone here that shows how to bypass the egr on an 85. But it also shows the factory routing.
