I don't think I'd worry about your existing ammeter. For one, it's not in series with the loads on the battery or alternator and, two, it's really just a voltmeter connected in series to measure voltage drop. After all, it survives periods of prolonged cranking, which can draw in excess of 150 amps without blowing up. You will probably need an accessory harness to hook it up though.
