The easiest way would be to put an inline fuse on the battery to power the relay. And like you said, tap into the horns signal to activate the relay. That is how I would do it.

I installed mine SAT afternoon, Works great.

I used a bosh relay I had laying around and tapped into the postive wire going to the fuse box under the hood. That was much easier than going directly to the hidden battery (used in line fuse as well). I didnt want to mess up the factory wiring by overloading it (or the oem fuse). But I used the factory horn wire as the trigger so no seperate button to push in a panic.

Its Super loud!
