the flasher doesnt need a ground though, its 2 prongs, input and output.
the flasher itself turns on and off just like the signal lights. basically the little metal inside heats up and then kinda cuts the circuit..then when it cools it completles the circuit...making the on.....off....on....off thing.
now that pulse that the siren wire is going to go through is going to create the horn honk. after that the wire signal itself is still positive, so the relay that i showed you how to write up will turn that positive signal to a negitive output...
the reason i say do it that way is that your relay setup is going to shoot a positive to the horn wire and then blow the fuse.
