How To Hook Brake Pedal to Car Horn (Prank)

If you’ve ever wanted to play a prank on someone, there’s a good chance hooking a brake pedal to a car horn has crossed your mind. It’s a fun way to play the perfect prank and make quite a noise in the process. 

While the thought has probably crossed your mind, the act of setting it up has probably seemed daunting to you. Don’t worry. Keep reading. We’ve got you covered with the steps you need to hook a brake pedal to a car horn. 

Make Sure the Brake Pedal Prank Works With Your Car

Because you’ll be connecting the wire to different parts of the vehicle, it’s always best to be in the know about certain aspects of the car. You need to check the following out to be sure you are making the right decision:

• Check the fuse in the brake light circuit: You need to ensure the power will be enough to power the horn.
• Check the fuse in the car horn: This is another important way to be sure the prank will go off without a hitch. You need to know the power will not damage the car. 
• Do Not Touch the Brake pads: All this prank calls for is a wire. You don’t need to mess with the brakes physically. 
• Use a relay: This is not completely necessary, but it will prevent either the brake light circuit fuse and the car horn fuse from breaking. 

If you’re fine with the above prerequisites, you should start getting the other items you need ready to make sure you are successful in making the brake pedal sound the horn. 

Get Some Wire Ready

For this to go off without a hitch and to avoid touching other components in the car, you’re going to need around 15 ft of wire. The wire will allow you to connect it between the components to get the result you want. 

The below method is without the relay.

1. Locate the brake pedal. 
2. Connect the wire to the brake switch behind the brake pedal. 
3. Feed the wire up to the steering column. 
4. Connect the wire to the steering column. 
5. Test by pressing the brake pedal to see if it works. 

Here is the method to make this work with the relay.

1. Place the relay below the hood of the car. 
2. Put in the brake pedal. 
3. Feed the wire to the relay. 
4. Feed the wire from the relay to the steering column. 
5. Test by pressing the brake to be sure you have done it correctly. 

These are both very simple processes, but it’s always best to exercise caution when you’re going through with it. The last thing you want to do is damage the vehicle. 

Health and Safety Matters

Playing a prank can be fun, but it can also cause some problems if someone is hurt. That’s why it’s always best to consider the following:

• Is it your car? This is crucial because if you’re doing it to a friend or family member’s car and damage it, you could be in line to pay a hefty bill. 
• Will the person on the receiving end of the prank be driving alone? The person might get a fright if they drive the car alone and the horn starts going when they press the brake pedal. It’s always best to have someone else in the vehicle who is in the know about the prank. 
• Could the person be on a busy road when they discover the prank? You need to be mindful of this. The person could cause problems for other drivers should their car start honking the horn without any need for it. 

These are just some of the most important things to think about before playing the prank. 

Always Think About Whether the Prank Is Worthwhile

Yes, pranks are fun because they can bring some humor into your life, but you always need to be aware of any potential issues that could pop up before considering using one. If you think there’s a chance the person is not going to take it as humorous, then that’s probably a good reason to avoid it. 

Moreover, make sure you’ve taken health and safety on board before letting the person get into the car. You might think the person will take it in good faith, but you’d be surprised how some people may react if they felt their lives were put in danger while they are on the road, and it happens.
