It sure seems to me that each terminal would be real specific. If the middle terminal is truly BATT then there should be only one other that is coil ground, and only one other that is the NO contact.
The relay coil is what is looking for ground through the horn button...the horn is looking for power through the NO contacts. Supplying a ground to the coil closes the NO contacts and powers the horn.
