Welcome to the forum Gary.I've been lurking on this forum for a while, and have read all 58 pages of this topic. I'm grateful for this thread because I experienced the "wobble", but didn't know it was from the Jeep. My front end on the motorhome went nutso when I pulled away from the side of an uneven road in Texas Hill Country. I was just as in the dark as most of the others on here, and when I get back to home base this fall will be adding the kit.
My question concerns those folks who make the alteration from the installed fuse/block to run a separate switch either inside or outside. That make much sense, but will that modification invalidate the responsibility of FCA in the event of future accidents (or?) because of wheel wobble? Would we have to prove our mod didn't result in the problem?

To answer your question, I don't think you have anything to worry about if you add a switch.
Wow, you read all 58 pages? It's a gruelling story to follow, and probably only interesting to someone that has experienced the violent shaking and looking for a solution. The first time it happened to me I thought either the motorhome's differential exploded or I had a blowout. The good thing is once the flat-tow kit is installed it eliminates the severe wobble problem. I have not seen any report of recurrence once the kit is installed. Since the kit was installed in mine I've traveled more than 5,000 miles that includes severe construction zones along I-75. The KL's steering has been rock solid.
On the switch question, I'm assuming you're talking about installing a switch that allows you to turn on/off the EPS (Electronic Power Steering) without having to insert/remove the 10 amp fuse that's part of the kit. As long as you insert the switch (12 volt, minimum 10 amp, waterproof) in series with the fuse, no one can point to that simple change as a mod that resulted in a problem. To minimize problems and keep it simple, I'd suggest keeping the wires short by inserting the switch next to the fuse holder that's part of the kit. However, if you've already punched a hole in the firewall....
Tip: As part of your departure checklist, grab the steering wheel and make sure it turns easily.
@bobged - At least my comments are reasonably inline with yours . Did I really spend that much time composing this post lol.
