Did some more looking around, the battery terminal on the electrical choke is empty, most likely where that wire came from, which explains why the choke doesn't work, and was disconnected entirely when I got the car, seems like the previous owner *really wanted* this electrical fuel pump, and paid a heavy price for installing it. Cleaned up the connections for the green wire, figured I'd humor myself and see if I could reassemble the broken alternator terminal, no luck, definitely gonna need a replacement there. Put the blue pin back in the connector after cleaning it, having alittle difficulty keeping it secured and not easily able to be pulled out.
I don't currently have a new connector for the end of the green wire, a new alternator that I can get soonish (preferably a part I can pick up from a store nearby), and I don't have spare wire or tools to reconnect the blue wire that's now too short to the electric choke. Do until I get a new alternator, this is probably where it's gonna sit.
