Instrument Panel Warning Lights With Modern Components

My 65 will soon have its fresh 302. It will have a 1 wire alternator. Does anyone know how I can hook up the warning "idiot" light in the instrument cluster for the alternator? I have an aftermarket voltmeter gauge, but would like for the light to work properly as well. Does anyone have any thoughts?

I'm not sure what the exact alternator is. It is coming on my crate motor.

Maybe I am wrong about it being a one wire alternator. We have been planning and working on the 65 for almost a year. For some reason all this time I thought it was a 1 wire alternator. Maybe it isn't.

What do you think?

Here is a link to a picture of basically what I am getting although it isn't the exact one. This picture just shows the alternator better.
