chadrc is your man when it comes to TBI vacuum issues, I'm sure he'll reply if you have a specific vac line related question, in the meantime that thread above has a lot of pics and good info (he posted those color coded pictures in there).

as sharpxmen said take a look at that thread.. this picture gives a good overview

there are also some more specific pics there. if you have any more specific questions just post them and ill do my best to help you out.

edit: saw your build thread so know understand you are trying to convert to mpfi.. will have to try to dig up mpfi diagrams tomorrow morning.. main things will be no egr and ccv rather than pcv...

I needed one for my 87 2.5 comanche.  None in repair manuals helped. Went to a dealership and they printed off a diagram of it from one of their books that was very detailed.  Try them.
