I was wondering if anyone has a diagram of a 90-92 speed density vacume set up? For a TPI L98 engine, that is? I have a crappy chilton but the diagram is very vauge and does not show the two ports comming from the passengers side of the car from the back portion of the fire wall. One of the hoses goes to the heater contol valve, the other one is a short vacume hose,not sure where it goes to??? Anyway, I would be greatfull to anyone who can post a pic of the diagram. My vaucme system has a few things tapped in to it because of my supercharger...FMU, boostgauge, second mapsensor for my boost retard.

Thanks!:hail:
