Do you have the ammeter? If you have the ammeter in hand, you can get the hookup instructions on line. If the ammeter is too low a current, you can add a shunt. Check DigiKey.

In any case, I'd rather not have an ammeter handle the full current mounted in the dashboard if that's your plan.

Or just buy something like this:

and hook it up in series with the alternator, i.e., in between the
alternator and the heavy wire which presently comes from the alternator.
If the needle goes in the wrong direction, just reverse the wiring.
