Vacuum lines
Just wonder if some one had a diagram of the vacuum lines for 1990. I know that i'm dumb, but I tore my car apart a year ago and have done some chromeing down to the motor and painted the car, I have one line that I can not figure where it goes. Just under the throttle body their is a sensor that has a 2 vacuum lines that plug in on one end. I know where the 2 that are together go. One goes to the egr valve. But on the other end has a place for a vacuum line with a metal clip. That the one. Thanks.

That is the vac supply line
Pulled mine out years ago but from memory runs back to a "Y"fitting under the plenum.The otherside of the "Y" goes to the fuel reg , the vac comes from the front of the two fittings on the pass rear side of the plenum.
Rear fitting supplies vac to the A/C control inside car
