I purchased a kit and there is no reading on the gauge once the car is started. I confirmed power to the red wire and the plug to the sensor fits perfectly. I have checked power and ground, both seem to be functional. Suggestions.

Another silly question. Is there any reason I cannot cut the mounting posts down so that I can install this in one of your mounting cups.(3202)?

Asked by: Tima
Thank you for your question. You can absolutely trim the mounting studs down if you have clearance issues and we would even recommend doing so if you are trying to mount the gauge in one of our mounting cups. Those studs are attached externally to the gauge casing so removing or trimming them will not harm the gauge.

Can I wire the warning light to a relay or something of that nature to shut off nitrous should it sense low pressure

Asked by: Tima
Thank you for your question. No, this gauge does not have any internal relay or output signal for the warning.

Silly question but just making sure. I assume the "warn" light is for when you lose fuel pressure? So alerts you when your pressure is low?

Asked by: Tima
Thank you for your question. That is correct, you can set the warning point, but it comes on when the reading drops below your warning point.
