    FOB beep....Not so Much
    4 Stars
    FOB beep....Not so Much
    To be fair it did beep with my FOB when I had tested it directly attached to the wires originally attached to my failing low tone horn on my 2016 F250 but I decided to add the included relay into the circuit due to the recommended 20A fuse to be used if wired directly to the battery, which is what I did, and alas no more beep with FOB unless door is ajar and then I get the normal double beep which works. Overall love the horn and with the failing low tone replaced and my new 20A relay directly wired Bad Boy securely mounted I will be better prepared to make sure those who inconsiderately pull out in front of me will know of my displeasure.
