I've been trying to add a siren to my I35, but I've not had any success finding a triger wire that will work to power the siren. I've got the arm/disarm chirp mode to silent and I tried connecting the new siren to the parking light flash output, but now when I use my turn signals, the siren chirps with the signal.
Anyone happen to know which color wire the horn output is? Or have any other ideas?
