Updated Universal Digital LED Fuel Gauge

James provides a walk through of the newly revised fuel gauge, as of May 13, 2013. Although not shown, all units shipping new use THREE LED colors: Green, Yellow, Red.
Also, the calibration and setup is done simply by touching a switch which connects to the back of the unit.

Will it work with 3.5 ohms to 110 ohms and backward as in the reverse to most common fuel gauges.
