ammeter with aftermarket harness?

Well, I'm getting done with my Ron Francis wiring conversion. I've also taken the time to make other common sense improvements like adding relays for safety for bits like the cigarette lighter, wipers, and headlights.

The kit I'm using completely ignores the ammeter in the dash, and I have a voltmeter in a gauge pod already. But it would be nice to have a functional ammeter just so I don't have to look at a dead gauge in the instrument cluster.

Can someone explain a clean way to do this?

Cheers.
