Please Help, Ok recently bought a 1989 Jeep Wrangler. Its awesome, I love it. But the 4wd light on the dash stays on, when I accelerate it goes out. Ok I checked the 4wd front axle shift motor, the vacuum lines were cut in two. So I went to the dealership bought a new vacuum line harness, just one problem. Where do all the lines go, I know where the 3 that hook to the shift motor go (yellow and Black) and I know the main connector goes to the transfer case. Ok well what about the red one, the blue one and the black rubber tube it has. I have looked everywhere and can not find where they plug into. Is there a sensor these plug into, what makes the light turn off on the dash. The jeep is a 2.5L with a 5 speed tranny. Any help will greatly be appreciated. Thank You.

Before you bother with replacing vaccum lines and such, check out something called a 4x4 posilok. It's an in cab cable enguagement system for the front axle shift motor. I think the website is: www.finishlinewest.com/posi_lock.htm

I bought one for my 88YJ (same as your 89) and it works great. I'm only mildly mechanically inclined and it took me 3h to install it! NSOR has them. Good Luck!

Oh yeah. The vaccum switch for the dash is that little blue thing mounted on the firewall that looks kinda like a battery.

God, I hated that vacuum system! It was so nice, rolling that harness up into a ball and chucking it into the trash during my engine swap


Anyway, your missing connections will go to the dash lamp vacuum sensor and to the engine vacuum source, which "powers" the whole works. ichris4x4 just identified the dash lamp sensor module. The engine vacuum connection is hanging near the passenger side of the engine. There should be a plastic tee that you can plug your harness into.
