Where does the horn relay go?
It serves as the relay that controls power to the vehicle’s horn. When current is applied to the relay, the horn’s power circuit is completed, allowing the horn to function and ring. Most relays are located in the fuse box underneath the hood. When the relay fails it can leave the vehicle without a functioning horn.

Do you need a relay for a horn?
The OEM horn draws somewhere between 1.5-2 amps. I tried the same with the sickspeed horn and the voltage drop was so high that the horn wouldn’t sound. So, yes a relay is definitely needed. #85 is the relay ground terminal.
How do you check a horn relay?

Where is the horn switch located?
Car horn switches, or buttons, are typically mounted in the steering wheel. Some steering wheel buttons are mounted off to the side of the steering wheel, but most are located directly in the middle of the wheel. Most horn switches are normally open, which means they only close when the button is pressed.

What is horn relay fuse?
The automotive horn relay, an electromechanical switch, operates the horn. This circuit prevents the large current of the main horn circuit from traveling through the steering column, which could be dangerous. Like any electromechanical device, the horn relay can wear out and need replacement.
