GS is right, they are not factory wired some dealerships put them on and some dont, we always install them on our bikes before we sell them, just like the one that captkirkis pictured above, but all the ones we install do have an inline fuse with them (which i would recomend) if it doesnt and your worried about your siren goin off just turn your ignition on for a second, then turn it right back off and pull your maxi fuse before your lights flash meaning the security is activated, then you can disconnect your battery and install a fuse with no screaming siren. Hope that helps out some. good luck.
