i have a 73 cuda and i replaced the fuse block with a modern one and because i didnt have a relay in it i did not know what the wires were for. so i put em together and left them. i want a horn obviously and i need to know on the relay itself what wires go where? i have a 3 prong without the key buzzer so if you are looking at it so it looks like this
(Dashes are the prongs themselves) what goes where IE?( 12volt constant,ground to steering wheel and to horns)...?
