US version incorporates a "side light" into the indicator, using a 21W/5W dual filament bulb?
Connect 12 volts across all combinations of the three pins. When you find the pair that makes both filaments glow, the pin NOT connected is earth. Having established this, connect 12 volts between this pin and the other two in turn. The one that gives the brightest light is the second pin for your two indicator wires.
