I think you are asking about the preheat hose. it should come from a shroud around your exhaust to your air box. the idea of it is to warm the engine up faster in winter time by puting warm air in the intake.
for those of us down here in the South and have know idea what a snow plow is and why you want it on the front of your MJ have long ago pulled it out of our MJ/XJ
