Wire the sensor to one of the 8 analog inputs, with its supply from the 5V sensor reference and its return to sensor ground, then configure the input in the app: sensor type, name, calibration and pull-up resistor.

The pull-up resistor is app controlled, which is what lets you run a two wire temperature sensor without adding a physical resistor in the loom. Set the wrong pull-up state and the sensor either reads full scale or reads nothing.

Steps:

1. Wire the sensor signal to a free analog input.
2. Take sensor supply from the 5V sensor reference, and sensor return to sensor ground. Do not use chassis ground.
3. In the app, select the input and set the sensor type.
4. Name the sensor so it is identifiable on the dash.
5. Turn the pull-up resistor on for resistive sensors, off for voltage output sensors.
6. Calibrate the sensor against known values.
7. Set the warning limit.

⚠️ Use sensor ground, not chassis ground. A sensor referenced to chassis ground will read differently under electrical load, and the error moves with engine speed.
