Mopar performance alternator 1or 2 wire???

What year car?
And how was it optioned, electrically?
Yes it makes a difference

1964 dart. All new wires, all new fuse box, connectors, etc.

Originally it had a radio from the factory but that was it for options. The bulkhead was actually disassembled and the connectors inside of it were replaced with new ones to be sure no 60 year old parts were being used electrically.
