Rally dash gauge voltage. 5v or 6v nominal?

Thank you, Rusty.
I had initially set it to 6v, so I will go with that. The extra volt may help with any voltage drop problems, anyhow.

Well, this place has tons of opinions. Get ready for someone to disagree. lol It's one volt. Right? 6 always made more sense to me since it's half of 12. But what do I know? LOL Hope things are going well in roo land.
