Extra connectors on the factory harness? Hmm...this might work for the voltage gauge perfectly.
I would prefer to have the gauge lights on the switch with the dash lights so they would come in together rather than running all the time. Then again, my dash lights are increasingly unreliable so I need to look at that too.
The wire I'm talking about is connected the dash light circuit. It's usually connects to lights on th column shift or the console. If your already using for that you could always use a Y connector at that connection.
Also if you're dash lights are dim you replace LED bulbs and will brighten things up.
