Vacuum line help

I have a 90 camaro 350 TPI. There is a small vacuum line located underneath the throttle body. Can anyone tell me where that vacuum line and also the one located on the MAP sensor is supposed to go? Thanks in advance

that is the egr solenoid vacum line. Goes from throttle body to egr solenoid. I think it is the front connector of the two on the solenoid , the other hose from the solenoid goes to the egr valve itself. The map sensor's vaccum line goes from the map sensor to a nipple on the side of the plenum.(on the passengers side).
