There's no vacuum line to the MAP on a Mass Air car. It instead senses Barometric Pressure. Tmoss has a vacuum diagram on his site, I think. I believe its veryuseful.com, but, you should probably find one of his posts (in this forum), and link to it from there to be sure.

also, where that vacuum line would normally go on say an 88, should be PLUGGED on your 90.
