    Not sure what yours looks like, but if they're anything like the FIAMM horns I upgraded to, there should be some short black wires included with each horn. They have a push on terminal on one end, and a ring terminal on the other end. Use this wire to ground one of the two male terminals on the horn to the mounting bolt/bracket.

    Then connect the other male terminal on the horn to the female oem connector from the car wiring harness.

    So, in short, your horns weren't grounded properly.

    Does anyone know which side the 500hz vs 400hz goes to?
