Blue - Yellow - Green Hoses

I was working on my 89 YJ when I found some spaghetti hoses that are blue, yellow and green - some of which were not connected - on the back left side of the engine compartment. Jeep runs fine. Anyone have an idea what these are for?

Does your 4x4 work? Do you have posilok? Sounds like 4wd vacuum lines to me.

That does sound like your 4wd vac. lines. One of them is a vent and should not be connected. Blue if I recall correctly.
