The engine I harvested for the yellow van upgrade did not have a fully connected vacuum system, due to lack of maintenance I guess.
Anyway this diagram I found was incredibly helpful in getting the system back to the original configuration.

Apologies to the owner of the image. The forum source that I found it on had no credits attached. Happy to provide credit to a verifiable source.
