Can't find hook up

Ok I can hear a hiss sound so I know i have a vac leak. I only get -10 vac and my car runs like poop. I called a couple of friends and checked the vacume line layout for the 1990 dsm's but I can't find where to plug this hose into. If anyone knows please let me know. It goes into the firewall and the other end is disconnected. I took a picture of it. My friend has the same line on his car but he can't see where it goes. Thanks.

That looks like your brake booster line. There is a large nipple on the back of your intake manifold that the pictured hose plugs into. That should solve your your cars problem as it is a rather large leak.
