- A more direct way of finding the fuel sending wire is to take out fuel sensor from the fuel tank and move the floating arm from full to empty while measuring the current of the wires. This should be done with electronics on and without ignition (key in ACC position). Fuel tank should also be empty for safety reasons, and trying to turn ignition on in this situation is likely to damage internal components.

- When you have found the fuel sending wire, simply connect the tracker to the wire using the Analog Input (AIN) wire from the device.
<br>
- After the tracker is connected, it must then be calibrated.

* Empty the gas tank.
* Use the Teltonika Configurator Status window, Maintenance tab where calibration table (with liters and voltage).
* Insert 0 liters, start engine, wait for around 30sec to sensor to find the equivalent voltage.
* Afterwards press the refresh button. Voltage will be filled in automatically. Continue by filling in around 5-10% more of fuel tank with the engine off. Turn the engine on and wait around 30sec.
* More measurements would provide more accurate readings later on. You can track voltage in Status > I/O tab to see how it fluctuates at any given moment.
