Questions on electrical diagram for air horn hookup to RXV
I bought this air horn about 20 years ago in Japan.
I haven't hooked it up for about 10 years and forgot how I did it.
I will be hooking it up to a Blue Sea 6 Circuit Fuse Box w/ Negative Bus that is connected to a 12V reducer on an electric RXV.
Not sure what the symbol in the red circle means.
Not sure why there's a toggle switch in the blue circle.
Also not sure why I need the switch in the black circle if it's going to be hooked up to the steering wheel horn button.
Can anyone walk me through it?
