Pin 1 - Black is ground. Pin 2 - Orange, drives the low fuel light. Pin 3 - Brown is the level sender.
Pin 2 connects to Pin 1 when the low fuel switch is activated, connecting the low side of the light to ground and turning on the bulb.
Pin 3 to pin 1 is a variable resistor, connected to the low side of the fuel gauge. The higher the resistance, the lower the fuel reading. A full tank is around 2.6 to 3.8 ohms; an empty tank is around 68-69 ohms.
