JK Hour Meter all of our JK's have it.
While in the Jeep shut the door. Turn the key to full on. Don't start.
Wait for the dash lights to go out. Push the thing in for mileage, push it through trip a, b, then to total mileage.
After you display total mileage, push and hold for about 5 seconds or so. Then Hour Meter will display how many hours on your Jeep.
