My 2013 required bypass switches, super easy to do.

The BLD works really well though, and truth be told I've never actually used the lockers in anything besides 4lo and even the only while out in the rocks.

 

This worked great, installed last month.
Took a while to do the wires.
Very little room to work and the wiring loom is tape, very hard to peel back.
Removing the battery would have been better.

JK Rubicon Locker Override Kit ? SEARCHERS 4WD SUPPLY AND OUTFITTERS

Everyone's driving needs vary, I get that... I believe that the primary reason for programming the diffs to only lock while in LOW range is SAFETY. Many of us use Hi Range to help us while on the highway(?). Our 1959 Jeep PU (Fire Dept) is designed / built to fight brush and forest fires. Its diffs are built to be locked 100% of the time. On the highway (especially on ice / snow covered roads) it is a BI!CH to drive through a curve or make a left / right turn at an intersection. It WILL TRY TO PUSH YOU STRAIGHT THROUGH THE INTERSECTION!!! We know this and have an SOP that we take it OUT of 4 WD at these intersections. It is usually okay overcoming the rear diff "push" at the slower speeds but in 4 WD the front diff actually "helps" the rear diff by pulling the Jeep straight as well. (It STILL influences the steering to try and go straight, esp on very icy roads, but without the power applied to it through the transfer case it can usually be managed) I wouldn't even begin to imagine how potentially dangerous this could be on a "modern" highway-driven Jeep! Maybe there is some trail conditions where a vehicle may drive better in 4 Hi Fully Locked but I've never been in that situation. Quite often the fire access roads are "dirt and mud" but can be fairly easy to drive on so we just shift into 2 WD and all is well. Aside from HEAVILY MODIFIED Off Road Jeeps there can never be a comparison between the "modern" generations and the "old guard" versions of Jeeps. (FYI... I have a dedicated (all 4 tires) set of studded winter tires for my '07 JK and very very seldom use 4 WD for highway driving (perhaps going UP an extremely icy hill if the rear wheels start to spin, but even then upshifting to a HIGHER gear will take enough power away from the rear to allow the Jeep to lug and maintain traction in 2 WD) I'm hoping this may offer some limited insight?
