Could someone do me a favor and tell me where the map sensor vacuum line goes? I bought a car (89SC) with the engine 1/2 way installed. I really need help! Thanks Derek.

Our sensor is a BAP (barometric absolute pressure) and does not use a vacuum line.

A you talking about the hose coming off the bottom of the tube from the MAF to the throttle body. IF so it goes over to the driver side valve cover. It is there to pull heated gasses out of the head and circulate it back to to motor to be used. Kind a like the PCV except it is open all the time where as the pcv opens when you push the accelrator.

There is no hose that connects to the B/MAP sensor.
