The turbo inlet vacuum line pictured connects to a hardline that runs somewhere under the solenoid rack and coils. But I can’t see where it goes without taking those off. Where does it terminate?

My car is nonsequential. For the record, the stickied FAQ nonseq vac diagram has that line going into the OMP injectors, but mine does not.

 

The hard pipe runs over the top of the engine to a short rubber hose that runs up to a nipple on the neck of the oil filler pipe. It is part of the PCV system. It is shown on the vacuum routing diagram on the underside of your hood -- On my 1994 manual transmission car, it is the hard pipe between No. 3 to 32:





Here is the hardpipe set:
