Are you sure it's the right wire?  Should be brown/black; and also
noticeably heavier gauge wire than the turn signal connections.

The wire from the control head connects to the brown/black to both horns;
and grounds it when the button is pushed.  Thus both horns see 12v across
their terminals only when the button is pushed.
