Horns have different connectors? 700 1991

My horn connections rotted out (rust belt). Got 2 used horns with different connections - bullet instead of spade.
1) Does one pair go to a particular horn (I would think not).
2) More importantly, I don't see how I tell which color goes to which terminal. Both pairs are blue/black and yellow. I guess blue/black would be ground but I don't see a minus (-) on either terminal.
Thanks.

    Most horns are wired sort of backward - power goes to the horn and gets grounded at the steering wheel.

    A relay may or may not change this.

    In any event, most horns only contain a coil and a contraption to rapidly interrupt and reconnect the circuit.

    (Unless it is an old aaoogaa horn, or an air horn)

    If your horn has two insulated connections as I think it does, I do not think that it matters which way you hook it up.

    You might try both ways to see if it makes a difference.

      OK, I'll give it a try. I guess if there was only one way then the connectors would have an indication on it or something to prevent the wrong connection.
