That would be a motion sensor or radar sensor for an alarm. It has 2 modes 1 for warn away if someone gets too close and 2nd is for full alarm trigger. If you dont have an alarm then cut it out, but if you do have one or plan on getting one then keep it.
Random Guy: "Is there anywhere that thing cant go?"
Me: "Yea, past a gas station..."
Wait a tic. What model Wrangler? The JKs have a gyroscope of sorts mounted under the console that is used for the ESP and ARM. Both read the sensor to determine if speed, steering wheel and body roll are all within specs.
