I just removed the center console from my TJ for a deep cleaning on the carpet and found this "device" tucked underneath the center console away from anyone's view. I realized it flickers when I turn my TJ on and then turns off once the car idles. Not sure what it is intended to indicate or why it is hidden underneath the center console.
My 4x4 low and high are perfect, car idles perfect, no knocking, wipers work perfect, lights, basically it is not tied to anything I can think of.
Thank you for any guidance on this matter.
