Issue with horn

the "ping" happens with and without the key turned on :S. I checked out the wiring diagrams at MyMopar and 71 Valiant, 70 Valiant/Duster, and 70 Dart/Swinger are all different. Could it be behind the kick panel and thats why i hear the pinging?

Note: my key buzzer doesn't work and i believe its on the same relay, could it be a bad relay then?

sorry for the high jacking
No problem. On my 72 Demon the horn relay is behind the drivers kick panel. From what I've seen the key relay is wired into that same relay. My wires are 12v is pink/violet... Signal wire to horn is green with a red tracer if I remember right. Black is ground from horn button. I replaced my horn relay and have to replace aftermarket horn button to get my problems fixed.
