In your 2012 Toyota Tundra, you can find the horn relay in the fuse panel located under the hood. The relay is part of the fuse holder, which is a plastic body that also acts as the relay itself. This electronic component is essential for the vehicle's horn circuit, controlling power to make the horn work when activated. If there is a problem with the horn relay, you may notice signs like the horn not sounding or hearing a clicking noise coming from beneath the hood.
I attempted to connect the fuse, and it seems to be working fine. Can you tell me where I can find the horn relay? I followed the instructions on the diagram for the "security horn" but had no success.
Is the security horn connected to the relay in the fuse panel?
