Mines like this, but i have the EML.Apparently you can plug the hole with a bolt and cable tie the sensor underneath and achieve the same with the light going off. Although I wouldn't do that unless it was safely shielded from the elements. I never had a light on my 182 with a Decat so it's just random as to whether it comes on or not.
Show offMines like that but the light comes on every now and again the disappears.
