The included alternator in the Concept One kit is NOT a 1G alternator. It IS a 1-wire alternator. Meaning it simply connects to the battery's positive cable for charging and does not connect to any external harness or voltage regulator.
If your gauge cluster includes an ammeter you must disconnect/bypass it or you will burn the cluster up with that alternator. Better yet, convert the ammeter to a voltmeter (www.autoinstruments.com
) or stick aftermarket gauges in your dash.
