Did you add any additional electrical loads from stock? Do you have factory a/c or power windows? I don't believe running the larger gauge wire from the alternator to the amp gauge and then from the amp gauge to the starter relay is the best idea, because your amp gauge is not designed to handle the increased current of an aftermarket alternator. You might get away with it, if there is no additional electrical load being supplied to anything non-factory.
Mad Electric's suggestion of routing the alternator wire to a main distribution point(usually the starter relay for us Mopar folks) and bypassing the amp guage in exchange for a volt meter is just tried-and-true great advice, especially if you are adding any additional aftermarket electrical loads to your car.
His advice for using relays for the headlights and any other high current devices is also great advice because it takes an additional load off your bulkhead terminals, wiring and switches.
I recommend that you go to his website and learn what he has to say about automotive electrical systems.
Just keep in mind that Mopar alternators are notoriously poor at producing power at low rpm's no matter who has reworked them. If you have added high current demand items like electric fans, fuel pumps, A/C, electric windows, you may need to retrofit another type of alternator capable of producing a large amounts of amps at idle speeds.
I found one that bolted right in and produces over 115 amps at a low idle and over 170 off idle. Sweet!

I think the post I found on another website a couple of weeks ago and can't find now said the poster cleaned and Noaloxed the bulkhead connector, then just ran an extra wire with fusible link from alternator to the starter relay to help carry the load, didn't change anything under the dash. Is that an option, will it charge and work normally? I assume the amp gauge wouldn't give a correct reading that way?
The problem with the bulkhead connector is that it has possible NUMEROUS problems. I just bought a 67 Dart this summer, and there's even some drop on the ign run/ regulator (dark blue) supply. This causes an overcharge condition and low voltage to the ignition.
Modern high performance large alternators (field/ regulator circuit) and big high performance ignition systems place and even greater stress on this circuit---just one example
