Dead end vaccum line

My 99 XJ classic has a vaccum line that leads to nowhere. Engine runs fine no check engine light plenty of power. Vaccum line has been like that since I bought the jeep. Just need to know where it goes if anybody has a vaccum line diagram or can tell me where it's suppose to connect to. I attached some photos that shows you the line runs from the driver side along the firewall and then dead ends at the passenger side just sittin there blowing out air.

Howdy Chuck! We miss you! OP, vacuum lines do not blow air out. (unless it backfires!) I'm about worthless on the newer. I can't think of anything that blows on mine, OH! the Valve cover vent to the air box! That indeed can blow.
