Theres a bunch of things wrong how this is mounted... If you can follow what im saying it'll be fixed.
First you need to flip that metal bracket around circled in red 180 degrees and mount it where the circle in peach color is, thats the designated spot.
Next the black arm with the balljoints on it (green line) should be in a position where its almost straight up and down.
Third the arm coming off the sensor (blue) shouldnt be at that much of an angle, it should all align right if you manuever it and mount it how i described in first step.
