I added this horn:
Use the existing power lead to power the relay
This is what I did, I have a separate power wire for the new horn through a relay, triggered by the factory horn wire so I have all of them blaring.
EDIT TO ADD:
After completing this mod, be sure to constantly remind your significant other that your truck is "Horny"
