How to connect a horn to a car?

Today I'm going to give you a simple circuit diagram which explains how to connect your horn to the car.you all know Free Circuit Diagrams 4U team has given thousands of useful car circuit diagrams. If we talk about this circuit, this circuit runs with 12v power supply.After fixing the horn to the vehicle tune the nail which is behind the horn to get a quality sound.( But some horns don't have such a nail so you cant tune them)

Note: 
           If you are a kid don't try this circuit Because 12V batteries contain high ampere 
          Always use high ampere wires to supply the current
