The dial lighting is accomplished via an electroluminescence panel behind the dial. T...

    It is a DC to AC inverter. Yes, you do need it for gauge dial backlighting. It is not necessary for gauge operation. The dial lighting is accomplished via an electroluminescence panel behind the dial. This panel glows when it is subject to around 100 volts AC. The DC to AC inverter takes 12 volts...
  • Do I connect both white wires together and tie to lighting?
