The small red tab is called a resistor pack. 3 wires connect to sensors on the tank, (which give you the 1/3 - 2/3 - and full readings on the LED panel inside).
The 4th wire goes back to the panel.
On my 17A - they connect as follows, probably yours is the same.
Red Wire - back to LED panel - connected to wire coming from in the trailer.
Yellow Wire - Lowest sensor on the tank (1/3)
Green Wire - Middle sensor on the tank (2/3)
Orange Wire - Highest sensor on the tank (full)
There should be a white wire connected to the tank as well (a bit away from the 3 sensors, that connects to the trailer frame as ground.
Hope this helps.
