Hello
I would like to add an additional horn as the car only has one and sounds very silly.
My question is does anyone know if I can simply splice into the existing horn wire or do I need to add a relay. There are no relays on these cars.
Thanks

I’ve put air horns on mine I just spliced in an put a higher amp fuse in

On mine t-jet, there is a relay for horn.
I also put 2-tone
