Hey Guys I need a little help with my vacuum system.

I just traded a guy for a 91 YJ 2.5l AX-5. I had a problem with the 4x4 light staying on. After a peak under the hood, I see that one of my vacuum lines to my VAC Disconnect is not hooked to anything. Their doesn't seem to be any where to hook it up. To make things worse, the PO painted over the vacuum system decal under the hood when he painted the Jeep. I also have an open vacuum port on my intake that is causing my rpm's to be a little high at idol.

I would like to get a diagram or something on the entire vacuum system. Since the 2.5 if fuel injected, what else does the vacuum effect?
 
Does your front axle have a center disconnect housing on it?

If not, the P/O may have swapped in another axle. If that's the case, you could just remove the dash bulb. I can't think of any way to make it function with the transfer case.

The 4X4 vacuum switch is on the firewall, under the battery.
