If it is slow to react or sounds sluggish after connecting it up, reverse the connections and see if there is improvement to the tone. It certainly won't hurt it to connect it either way. Most folks don't sound the horn very long. On a motor driven horn, the motor will change its direction of rotation when the polarity is switched. When they get used to going one direction and wear in that way, it can sometimes change the tone when it goes the other way.
