the thing is, its a schematic diagram which means you read it like a blueprint. find the part you know and follow the line until you get to the next junction or part. as I've heard before, think of vacuum as a commodity which is supplied by the pump. If you have a gauge I would hook it up directly to the vacuum pump to see what it pulls. they say about 22 Hg. mine only goes to 15 or so. using your Mityvac connect to different lines until you find where it DOES NOT hold vacuum. remember one goes into the cabin for clean atmosphere so it will be open always. Brown I believe goes to the key for fuel shut off. yellow with green or red stripe is for door locks, etc.
you should be able to hook up to the fuel shutoff pod while the engine is running and when you pull a vacuum it should shut off the engine.

I would guess you have a leak before everything splits to all the various functions since several are not working. hope this helps
