Alternator wiring

My 71 Demon has 3 wire connections and was hoping someone could help me .
Of course the main hot post, then there are 2 smaller spade connections. I THINK one goes to my voltage regulator. The other one, I have no idea what it's for.
I no longer have a ballast resistor or the factory ignition box.

Wondering if anyone knows what exactly the spade connectors go to.....and if I could eliminate either one, or both.

Electrical is like bodywork to me. Not my thing for sure.
