TR6 Alternator wiring

I replaced my stock a 1971 TR6 Alternator for one sold by BPNW. It's a 60 Amp mode and only uses the three wire pins. It didn't come with a diagram and my wiring diagram is out of date and not the same partly because the new one has the pins in a different angle. Does anyone have the correct setup or attachment pins for my ammeter and the fuse box wire? Any specific information would be useful so that I don't mismatch and burn up my new part.
 
Brown yellow(and jumper) go to IND, if it were a Delco alternator. Thinner brown goes to BAT. Large brown/white goes to +. You may or may not have a ground. I have added one to the - connection since it’s there.
 
The thinner brown would be from the fuse. Brown/w yellow just goes to ignition warning lamp, along with white from the ignition switch. Heavy brown/w white comes from the starter.
 
This is one of my perhaps dumber questions. Anyway if I put one of these alternators on my tr3, will the car run without a battery in like an emergency situation?

When the engine is running the battery is being fed a charge, the alternator is feeding the power. Theoretically, yes. The engine will continue running while the battery is removed. I’m not sure it’s ever a good idea though. I don’t know what affect if any it will have on the alternator itself, not having that back feed from the battery.
