Thanks for the further explanation. Usually when the 1st snow fall hits, I go out to a large parking lot, turn off the traction control and do some semi donuts, just to get used to driving in snow again. I never seemed to have a hard time swinging the back end around with the traction control off while in 2WD, but I guess I never really continued to give it gas to continue to go around in circles as well, so I really never noticed the traction control kicking back on while it was off. I guess I was doing more of the Duke's of hazard 180-270 deg whip around than trying to do a full 360+ deg donut.

I'll be doing Silver lake this upcoming summer which is sand. From what I've read, most have said for sand is to put it in 4WD Hi, turn off traction control, and air down your tires. That's why the need for this ETC kill switch seemed kind of strange to me.

for deep soft sand, auto transmissions can get hot if not in 4LO. Lots of posts from people with pre-2012 getting the hot oil light on. From 2012, the auto trans got a much more effective cooler.

So can you provide instructions on how to wire the switch?

No added switch on mine, no problems in the dunes. Using the disable switch (long press) on the dash is usually advantageous if using 4HI. I've never noticed the BLD portion of traction control causing excess brake activity or wear -- Just did brakes at 75K and they could have went to 100K.

I hooked up a switch when I bought my 2012 JK. It is much nicer to drive a JK like a real Jeep. I don't turn it back on except for in inspection. I am very disappointed in this new technology. My older Jeeps are much better at being Jeeps. If you hold the traction control button down for 7 seconds in 4hi, you will turn off the systems if you keep it below 45mph. It will say ECS OFF on the dash. In sand you want 4hi to keep up your wheel speed.

Here's a couple interesting links on the subject:

There's a cool video of snow drifting with just the normal ESC off (hold ESP button for 5 seconds).

This is an 2014 update to a JP magazine article. The table showing what's active in each mode makes it easier to understand -- Jeep should have put a table like this in the manual.

You can use the switch in 2wd for the dunes snow or what ever you want. You can't turn it off by pushing the button while in 2wd. It's not just the traction control it's the ESP and ABS and the traction control.

You shouldn't need 4wd for the dunes. It's mainly air pressure and traction. 10-12psi and a locker will do wonders.

ESP is the combination of Traction control and ABS. They're not 3 different items. I'm also not understanding why turning off ABS would have any benefit.
