Since American Autowire did not show any Ammeter possibilities in their wiring diagram, I called their tech support about my question. I was told that they did not include any info about ammeters because they viewed them as unsafe in a modern setup with large capacity alternators, such as I will be using. They advised to delete or leave uncionnected, the ammeter and to install a volt meter either in its place or elsewhere in the truck. That all sounds great, but does anyone know of a voltmeter I can put in the stock TF dash in place of the ammeter?
