1995 Jimmy vacuum line mystery.

There's a vacuum reservoir under the hood on the driver's side. There's a vacuum line coming off of the back that is unhooked and I can't find where it goes. I'm attempting to upload pictures for the first time. With any luck you should be able to click on those lines of code below and see the two pictures I uploaded to a hosting site. My fingers and toes are crossed.
