New ignition switch installed...brown wire?

Where does the brown/yellow wire go?

Wiring diagram shows horn, but I already have a brown/yellow wire hooked up. Key buzzer (which I don't see)?

You appear to need a new carbon pin....

One of these? Ya, I bet. $50 though. Uggh.

I have a feeling that extra brown/yellow is for the key buzzer:
