One goes to the MAP sensor on the inner fender. If your in doubt replace them most crack over time. Usually just wet the rubber and run your fingers down it. If you have black on your fingers there dry rotted.

Are you taking about the two plastic vacuum lines that come out the firewall? I dont have a map sensor since i have the digital cluster dash
