Sorry call me dumb but which is the high and which is the low? I assume
0.3bar is low and 0.9bar is high.

Boy some days I just feel dumb.

Grounding that would make sense - in my '90 I was having trouble witht he
buzzer going off - Boston Bob told me how to ground the sensor out in the
engine bay. So in this case it would make sense to ground it in the gauge.
