Oh ya when I wired mine up it came with a relay so I ran power from the battery to the relay, relay to compressor, relay to ground I believe and then relay to horn button. I then tapped the power wire from the battery to the relay for the horn button and it worked perfectly.

i'll consider this as a second horn, i can't imagine if this is the only horn you have and you accidentally let someone use your car for a behind the wheel exam at the DMV.
