Unplugging Rubicon e-disco sway bar wires

Checking if anyone has disconnected their Rubicon electronic sway bar wiring and if so if you've had any problem leaving the connector disconnected.

My sway bar electronics and connector shorted and melted, causing all kind of electronic troubles.

Since I'd been disconnecting manually for years I didn't want to spend $1,000's on the repair and the dealer just cut off the connector. The Jeep is running fine according to them (haven't picked it up yet) but they're not 100% sure it won't throw codes in the long term as that system was part of the canbus network.

My feeling is that it'll be fine, but I wanted confirmation if possible.

Oh, and I disabled the swaybar system with my ProCal a while back.

I was sitting on the beach and a lady next site over said your jeep is smoking! Sway bar plug melted down. It even had power hours after the jeep was turned off. I pulled the fuse, cut the plug off, and taped off the wire ends. Been almost a year now without any issues. Just drive around disconnected.

as long as you used the procal to disable the system it should be fine. you can actually remove the wires at the fuse box. reverse this.

Which begs the question: why didn't the fuse blow when that thing shorted?

Wondered the same thing when mine melted down.

I would really like to remove the plug but the pictures aren't really clear. Where are those plugs? Are they under the fuse box?

Yes, if you lift the TIPM fuse box, there’s a rat’s nest of wire looms and connectors under it.

Mine died a while back. I just unplugged it and used the procal to kill the dash light. No problems. Swapped in an EVO no limits kit. It works great. Way better than disconnecting sway bar links (which I tried and hated before getting the EVO kit).

Just got my Jeep back. Leaving the connector unplugged for now, sway bar is disabled via ProCal. And fuse is out.

I may trace those wires later and just take them out.

Wow, that is a bit worrisome.

At least yours was easy to find, what with all the pyrotechnics!

Mine took some detective work to find the problem, at stealership hourly rates...

I've zip tied the connector under the air box, will trace and remove the wires for good measure at a later date.

Yea and I was sitting less than 20' away when it happened - Got lucky. I just cut and taped off the end which I don't really care for. Let me know how removing the wires go. Planning on replacing it with this sooner or later:

Will do. I may go the EVO route myself.

Week before moab this year, sway bar light made it's presence known. Removed motor, I was rained on. Disassembled the motor, there were black marks on the circuit board where the magic smoke was released. Made a cover out of HDPE using same hole pattern. Drilled a drain hole in bottom of the housing. Wrapped plug in a bag and tied up. Installed RK disconnects that came with the lift, that I didn't install when I did the lift.

Superchips had a great deal on their bling for EJS. Acquired a flashcal and turned the light off.

I will not be doing another rubicon e-disco.

The e-disco and its connector aren't waterproof, so I'm guessing moisture caused the short circuit. And since there's a canbus circuit going to the e-disco, it got shorted as well which causes all kind of weird electrical issues including battery not charging, Jeep not starting, key fob not working, alarm going off, dashboard lighting up like a Christmas tree.

Why would someone think that placing an electronic circuit in a non waterproofed housing below the front bumper of an offroad vehicle was a good idea? Couldn't they have the logic in a central computer safely tucked away with just the actuator exposed, like they did with the lockers?

Probably designed by an engineer who doesn't even have a driver's license.

Yes the plug is vulnerable to moisture, so I had already treated it with dielectric grease during one of the repairs. it still melted down.

And to fix it: sway bar: $2,000. Hardness $380. Labor 10-15 hours.

So at least $4k.


Alternative: Manual disconnect links: $150. Or, EVO air system, valve etc: $375.

I've been disconnected for a few months now since my smartbar shorted out. I finally pulled the entire sway bar last night and it was filled with mud and rust and the plug was melted. I just posted a thread about it. I wrapped the plug in saran wrap, taped it up and zip tied it up in the body. Should I be worried that it's still getting power and might be further damaged? Also, the bolts to disconnect the swaybar from the body WERE NOT 16mm, they were 5/8.



Evo does a mechanical disconnect that you screw/unscrew for like $90.

I went with the EVO after cleaning the gunk out three times. Procal to turn off the sensor and sometime next week I am going to pull the plug off of the fuse box.

Remove the fuse. It's fuse J11 on 2012+ Jeeps.

This eliminates the permanent battery positive feed, unfortunately there is also an ignition positive feed to the connector. Best is to remove those wires under the TIPM. I plan on doing so soon and will post a how-to.
