            Difference of Pressure and Non Pressure sensor of AlcoSense Zenith?

            No difference in function or accuracy. 

            Pressure - with red, black and white wires.

            Non-pressure - without wires.

            The non-pressure sensor wont work in the unit that requires a pressure sensor, and vice versa. You will have  to remove the sensor (the rectangular board you'll first see) to see this.
