Yes, the voltage regulator is integrated into the PCM. The VR sees
only the field signal from the alternator, so amperage doesn't matter.
Just make sure your charging circuit wiring can handle it (I'm sure
you knew that).
FWIW, if your PCM VR ever fries, don't replace the PCM. You can clip a
wire or two and hook up an older style voltage regulator quite easily.
