Vacuum connector from NP231?

[BRC 88MJ]

I've got an NP231 from an XJ that had the vacuum disconnect on the D30 front. I'm swapping the axle and 231 into my MJ but will be deleting the vacuum disco.

 

There's a connector on the driver's side of the TC that looks like it's vacuum lines. What was this for? Is there going to be a problem if I don't reconnect these lines? The vacuum lines in the harness that I pulled were broken anyways.

 

Thanks.

You don't need to do anything to those vacuum ports, muck can't get through into the transfer case. You can unscrew the vacuum switch if you like, and replace it with a plug similar to a 231 from a non-disco jeep.

Thanks for the advice. Sounds like a good plan.

I just got 4 of those little rubber vacuum caps and covered the connections and left the switch where it is.

Just be sure to trace and plug the vacume SOURCE!!!

Yeah, I still have to do that on my 90. I just sorta ripped out all the lines without seeing which one lead to the engine. :(

Do a later model SYE and it does away with it too :brows:
