Whether it’s April Fool’s Day, a birthday, or just a run-of-the-mill Tuesday, sometimes the urge to pull off a well-natured prank is irresistible. One timeless practical joke is wiring a friend’s car so the horn honks when they press the brake pedal. Before you dive into executing this classic hiccup in someone’s driving routine, it’s important to remember that safety comes first, and you should only perform this prank on someone who will take it in good humor and in a safe environment.
In this comprehensive guide, we’re steering you through the lanes of this prank, ensuring you don’t hit any bumps along the way. So, buckle up and get ready to inject some harmless fun into your friend’s day.
Before You Begin: Things to Consider
- Get Permission: Always obtain permission from the vehicle owner before tampering with their car. Surprises can be fun, but respect is paramount.
- Safety Check: Be sure the prank will not create a dangerous situation for the driver, passengers, or others on the road.
- Know the Local Laws: In certain jurisdictions, tampering with a vehicle’s operation, even as a prank, can be illegal. Make sure you’re not braking—er, breaking—any laws.
Tools You’ll Need
- Screwdriver set
- Electrical tape
- A few feet of wire (gauge matching the horn’s wire)
- Wire strippers/cutters
- Multimeter (optional)
With the right tools and a little bit of automotive know-how, you’ll be ready to rig the horn in no time.
Step 1: Access the Wiring
First up, you need to access the wiring under the dashboard. Use a screwdriver to remove any necessary panels to expose the brake pedal assembly and its wiring. Exercise care not to damage any components as you do so.

Step 2: Locate the Brake Light Switch
The brake light switch is usually located near the top of the brake pedal. It’s responsible for activating the brake lights when the pedal is pressed. You’ll be attaching your wire to this switch to trigger the horn.
Step 3: Identify the Wire Colors
Once you’ve found the brake light switch, identify the positive wire – most likely the one that leads to the brake lights. Consult the vehicle’s manual or an online forum specific to the car’s make and model if you’re unsure. This wiring resource from The12Volt can be immensely helpful in identifying which wire to target.
Step 4: Cut and Strip the Wire
Using your wire cutters, carefully cut the brake light wire. Strip both ends of the cut wire, as well as one end of the additional wire you’ve brought along. Keep in mind; this step will temporarily disable the vehicle’s brake lights, so speed is of the essence in executing the prank.
Step 5: Connect the Wires
Here’s where the fun starts. Take the additional wire and connect one end to the side of the cut brake light wire leading to the brake lights. Tape this connection with electrical tape to secure it. The other end of this additional wire will be run to the car horn.
Step 6: Locate the Horn Wire
Under the hood, find your car’s horn. It usually looks like a disc or a small trumpet and will have at least one wire connected to it. This is the wire you’ll be connecting to the additional wire running from the brake light switch.
A pinout diagram can be a life-saver if you are struggling to identify the correct wire.
Step 7: Make the Connection
Run the additional wire from the brake pedal up to the horn, avoiding any hot or moving parts under the hood. Use your wire strippers to splice the end of this wire into the horn’s existing wire. Make sure the connections are tight and secure with electrical tape, but remember: this is a temporary hookup.
Step 8: Test the Setup
Before reassembling everything, it’s testing time. Have someone gently press the brake pedal while the ignition is on to see if the horn honks. Make adjustments if needed. Once you confirm everything is working, carefully reassemble the dash and hide any visible wiring.
Step 9: Surprise and Reveal
With the prank set in motion, all that’s left is to watch your friend’s reaction as they unwittingly serenade every stoplight and stop sign they encounter. Capture the moment (safely), and be ready to share a good laugh.
Step 10: Restoration
As with any good prank, quick and complete restoration of the vehicle to its original condition is essential. Reverse the process you completed earlier to remove the additional wiring and reattach the brake light switch wire.
A Word of Caution
While pranks can bring a burst of laughter to an ordinary day, always consider the potential fallout. Every vehicle owner responds differently to unexpected surprises involving their ride. Plus, the joke should end before hitting the road to ensure the safety of all.
Should any complications arise, or if you’re not confident in your ability to perform this prank safely and correctly, it’d be wise to seek help from a professional mechanic or, better yet, decide on a less technical gag.
