That varies by the installer. Some might wire it into an unused slot in the fuse panel, or they might piggyback it off an existing one (which, personally, I do not recommend). My vehicle isn't a police vehicle, but I have additional lighting on it, and I bought a Blue Sea fuse panel, and basically installed an additional fuse panel.
