If I remember right there is a cluster self check/calibration you can initiate. Well at least in the durango/dakotas but the ram clusters are slightly different mostly that maintenance required light.

Well thank you guys for the recommendations. Since the light is controlled by the cluster Im wondering if the light goes off a certain point in the gauge. Like if the needle hits a certain spot it trips the light. I know factory gauges arent too accurate, maybe its off and its tripping that light. The self check seems to be in the 98+ that has the digital odometer.

Every 2nd Gen I have been in, when the pressure drops under 20 psi the dummy light turns on.
Like HeyYou said, it is supposed to happen around 7~10 psi, but that hasn't been my experience. One sure way to know (as someone else stated) is hook up a mechanical gauge (yes, again) and mount it inside. There is room for a tee where the sensor screws into the block, then you can have both gauges going. It works well, and let's you see just how far off the stock gauge is.

"But I also checked O'Reilly's website and they have one for the gauge AND Light."
The only difference I can see in the descriptions of the one you bought, and the one you didn't buy is this:
"Pressure switches calibrated to match O.E.M. actuation PSI."
Maybe, the one you bought...e.g. "for Gauge only" is not calibrated to match the factory actuation levels for the warning light?
It's not uncommon for after market parts to be designed to cover a broader range of vehicles than OEM parts

According to the '97 schematic I found, the sensor is depicted as a potentiometer with the gauge tied to one end, and the lamp on the other, with the wiper grounded. The other side of the gauge and lamp are tied to ign-run.
You probably need the sensor designed for the gauge and light.

Another Job Well Done
Way to go, and thanks for letting us know.
