I think you are saying that you insert the sensor into the hole in the bracket from the front with the plug into the bracket. Then you take the wired other side and plug it into the now mounted sensor from the rear. That is logically the
​​​only way I thought it would mount, too. Problem is that when I look into the bracket hole, it is way too small for the sensor plug side to fit into the bracket hole. Only the pointy end fits through through the tiny hole. Of course, then there is nothing holding the sensor into the bracket . How much does the sensor stick out the front of the grill when properly mounted?
