No adapter on a 390.....Oil Sensor is screwed to top of oil filter housing.
Plugged as in the oil access hole is blocked I doubt it because yes the idiot light did work (meaning it wasn't on) prior to this project.

I understand that the sensors are very prone to be bad, even new, but I have gone through 3 already.
I know the gauge works because if I ground it the needle pegs. I'm also guessing because of this I also have the correct low voltage needed from the volatge regulator.

Am I missing something?
