Yep, you were right. I disconnected the wires from the gauge one at a time and sure as chit it's the ground from the sensor and ground for the gauge that is making it work. So, my engine has been grounding through my rp gauge all this time. Does anyone know what pin on the ecm is the sensor ground by chance?
