NEED HELP FAST! What is this on the wiring schematic? Wiring the car now

GEEZ, I made a horrid mistake, here. That item IS NOT only the key in buzzer, it's also your horn relay. The buzzer part of the equation is the end terminal, and is why it's broken off in the photo---to disable the buzzer and still allow the horn to operate

I've had about 5 hours sleep in the past 48 hours.
