So, after replacing the rack and pinion on my '06 KJ, I found this guy hanging out off to the side, detached from whatever it is supposed to be connected to. I must have snagged it pulling the r&p out and not noticed it. I can't seem to find where it is supposed to go and can't find anything in the FSM about it. It connects to the front differential, so I assume it is a vacuum line to engage the 4 wheel drive? I just don't see the connector it goes on. Also, if this IS a vacuum line, would it being disconnected affect other things like the turbo by not having enough vacuum?
Anyone know?
