> i also got a phantom af guage, was wondering, black is ground, red is…light? and purple is signal. so…where do i connect the red to? thats if its for the light signal, if it is, which is the best wire to pick out of the pack?

Red is power. It can be connected to any positive power source really depending on when you want the gauge to have power.

I think a lot of people have used the cigarette lighter for easy access (and it is activated by key turning in ignition, which would be appropriate), i’m almost positive on this but someone may correct me if i’m wrong.

And no problem, dk…

Good luck.
