By the way. The ground side of the relay in this diagram could be used for switching with the horn button as well. Most steering columns (horn buttons) switch ground not the positive. Power would be applied to pin 86 and the horn button would be connected to pin 85. The fuse going to pin 86 would most likely be in the fuse panel where you would get power. If you were taking power directly from the battery, you would still need the fuse shown in that diagram for pin 86. Don't forget that the fuse for pin 30 would still need to be 40+ amps if your two horns draw 20 each and you would need a high current fuse holder as well. Something like this;
