But if you have a 60-amp alternator, the wiring through the ammeter to the battery may be getting a bit warm. The 12 gauge wire in those harnesses is rated at only 20 amps.
In my coupe I found the ammeter wires are only 16 gauge, like the rest of the car (=10A). I should replace them with #10 for my 30A alternator. Maybe one day.
