This fuel level gauge has a delay function circuit that does not cause flickering of the LED display because the tank is sloshing during driving. Blue LED can be clearly shown in strong sunlight.

The gauge is fit to a resistance type fuel level sensor, and the measuring range of the sensor is ≤ 2KΩ.

It can be adjusted to fit your car.

• ① Red Wire — Connected to ignition switch ACC
• ② Green Wire — Fuel level sensor signal line
• ③ Black Wire — Battery negative electrode
