I am having a issue with my 4wd not working I looked under my jeep this morning in the snow and the vac lines werent attached. I was wondering if anyone has pictures of how these are supposed to hook up?

 

Theres a plug that just connects to the diaphragm ....

 

Unless it isnt there, i have been lucky enough to avoid the cad systems so i couldnt tell you which goes where, sorry

 

Thats no problem I think its fixed now I would not suggest putting screw driver bits in vacuum lines to plug them..

 

So you just plug it back on ?

 

when I bought my 90, it was missing the adapter piece (vac lines to axle .. hoses just hanging)

I went to a junkyard & looked at 1, used rubber hoses as links, 4x4 worked fine after

I sold mine .. so cant tell you what color hose goes where .. JY closeby ?

hopefully someone on here will go look at theirs for you .. its very easy to hook up.

i bought a JY adapter, but it didnt fit too good, bulk rubber hose did the trick .. it worked better after i gently sprayed cleaner into vac lines & diaphargm ports, they were plugged a bit from dirt .. that dirt wouldnt allow 4x4 to kick in at 10k elevation .. good luck, its easy

 

Also another question theres a trans switch what does the switch do

 

The adapter was there the people i got it from plugged the vac lines once i unplugged them and re attached them to the vac unit it worked. Now i just have to figure out all the other little stuff.

 

A great day to climb under the jeep in fresh snow.

 

Trans switch the speedometer?

I had a small ma and pa shop take the CAD system out of my YJ when I had it. I think they put XJ shafts in there. Never worried about that again. I had it pop off before. Got stuck in sand because of it. Worth looking into.

 

When I switch my axles out this spring that whole setup is hopefully going away

 

It says trans power

 

Just do this and be done with it:

The Power/Comfort switch has nothing to do with your 4WD system BTW.
