Hey, I just bought a new car horn. I'v been trying to get this thing installed. I got the wires where I need them to be except for the red wire. It says to put it into a 12 volt spot on the fuse block, or put it to a line that makes 12 volts.

I really have no idea how to do this. I would like some advice, before I go kill my electrical system.

 

Are you replacing your stock horn?
