Skezza Posted May 27, 2014 Report Share Posted May 27, 2014 What colours are the wires? I assume one is black, one is red and one is.... green? yellow? white?Either way, one will go to live, one will go to ignition and the black/brown will go to earth. Work it out from there.

The signal it is measuring is your permanent live but the LCD plus backlight is powered by your switched live.Hope this helps. Quote Link to comment Share on other sites More sharing options...
