The main vacuum line is behind the intake manifold, on top of the engine. It is also near where the large rubber brake booster hose comes out of, and goes to the master brake cylinder. It comes off of it, and then runs along the firewall until it gets to the passenger side. Then it bends and goes down near the battery. It is a hard black plastic line. If you start looking near the battery and work backwards, that might be easier for you. Or look along the fire wall for it and trace it both ways, to the battery and then to the engine. I do not know of a wrirte up to lead you to.
This line goes into the car, through the passenger side. If you remove the glove box, you will see it inside the car then.
