I also figured out how to get the low fuel light to work with the Koso LED indicator panel. Here is a little diagram I made if any one is interested: For those who are curious about this stuff… The stock gauge uses a 7w Bulb which has the correct "power requirement" to work with the low fuel "thermistor" in the tank (when the fuel drops below the level of the thermistor it heats up and lowers the resistance of the circuit). With the Koso LED indicator panel the low fuel light will always be lit as the LED requires such little power to activate. I tried different resistors but there was alway a tiny bit of power getting through and that was enough to light the LED constantly. The relay allows the LED to be on a separate on/off circuit from the thermistor. I tested it on the last tank and it worked, time will tell if it continues to function properly. So now I have a fuel gauge and a low fuel light, just like stock :) Going without the low fuel light on the Koso gauge isn't really a problem as the fuel level is consistent (thought not necessarily accurate to percentages of the actual tank level) and the Koso gauge has a user adjustable low fuel warning. However it takes over one of the gauge readouts (for example, if you wanted to have the gauge on engine temperature) and starts flashing when you hit the specified percentage of remaining fuel. A little annoying… now I can postpone the fuel level warning until 10% and rely on the low fuel light. -End of long winded and probably unnecessary explanation.
