Command Trac Problem

The vacume motor on my front axle works. I replaced the vacume switch on the transfer case. The vacume hoses (plastic were tore up and modified) have been replaced. I guess I hooked 'em up wrong. Where do the hoses hook to the switch????? I can't find a schematic ANYWHERE!!!!!!!

'90 YJ, 4.2 liter, 4"Pro Comp Lift, lookin for other goodies.

i took out my disconects but if i rember right, the hoses that goes to the trasnfer case only goes in one way. then the other end just goes the the vacume disconect on the axle. run the motor so that there is vacume in one of the 2 hoses to the axle. make sure u are in 2 wheel drive. then conect the side with the vacume to the pas side inlet and the one without to the driver side. you are shifting the sleeve to the left (driver side) when in 4x4. then pull the shifter into 4 wheel and see if your ingagement light turns on. hope that helps

I also replaced the hoses on my 89YJ. I tried to replace each hose individually with no luck. Purchased a replacement hose kit from the dealer and all works well. As stated by jpwranglr9, with the replacement kit it only attaches one way.
Put the plastic lines inside a rubber hose. The plastic hose can be distroyed by battery acid that can leak out when you are off roading.
