'62 Grand Prix horn wiring

I'm hoping someone with a '62 GP or better wiring knowledge than I have can help.  I didn't take any pics or make any diagrams before ripping all the wiring out of the car.  I'm stumped on the horn wiring, and I'm probably over thinking it, but can't figure out how to wire it up.  The first horn connects to the horn relay with a green wire, and a black ground wire.  The second horn has only one connector, so does that connect to the same green wire?  If so, does it have an internal ground?  I have the diagrams, and shop manual, etc., but they haven't answered the questions.

Help?

Thanks!
