CAD axle Q's??

[ParadiseMJ]

Got a 88 MJ and 90 XJ. Both CAD axles. If I convert the axles to always locked, does that mean:

 

• Is the Jeep always in 4x4 or does the transfer case linkage contol that now?
   
  Do I still need any vacuum lines in that area (do I just cap them all)??
   
  Does it create any more stress on the system as a whole??
   
  What controls the dash light (Part Time)??

Thanks in advance.

  Transfer case controls it. The CAD system was tossed out in the early 90s.

  You can cap everything.

  Nope.

The dash light is controlled by vacuum, but who needs the light?

 

Thanks in advance.
