This guide outlines the process of cutting the brake sensor wire on an Ebox dragster. This is an advanced modification and should only be undertaken by individuals with significant experience in automotive electrical systems and drag racing. Incorrectly modifying this system can lead to serious safety hazards, including loss of braking function. Proceed with extreme caution.

Understanding the Implications

Cutting the brake sensor wire bypasses the electronic brake system's normal functionality. This means your brake lights will not illuminate, and the car's computer may register errors. This modification is typically done to prevent electronic braking interventions that might hinder performance during drag racing. However, it renders a crucial safety feature inoperative. You are accepting full responsibility for the risks involved.

Tools and Materials

• Appropriate wire cutters: Choose cutters suitable for the gauge of the brake sensor wire.
• Electrical tape: High-quality, weather-resistant electrical tape is crucial for insulation.
• Wire connectors (optional): Using connectors instead of directly splicing the wire offers easier reversibility.
• Multimeter (highly recommended): A multimeter allows you to verify the wire you are cutting and to check for continuity after the modification.

Step-by-Step Procedure

1. Disconnect the Battery: Always disconnect the negative terminal of the battery before working on any electrical system. This prevents short circuits and potential damage to the car's electronics.

2. Locate the Brake Sensor Wire: Consult your vehicle's wiring diagram to accurately locate the brake sensor wire. Improper identification can lead to irreparable damage.

3. Cut the Wire: Carefully cut the wire at the chosen location. Make a clean cut to prevent fraying.

4. Insulate the Ends: Thoroughly insulate both ends of the cut wire with electrical tape to prevent short circuits. Multiple layers of tape are recommended.

5. (Optional) Use Wire Connectors: If using connectors, carefully crimp the connectors onto the wire ends, ensuring a secure connection.

6. Reconnect the Battery: Carefully reconnect the battery's negative terminal.

7. Test the System: After reconnecting the battery, test the brake lights to confirm they are inoperative. Use the multimeter to verify the wire is disconnected and there are no shorts. The brake lights should NOT illuminate.

Safety Considerations

• Always work in a well-ventilated area.
• Wear appropriate safety glasses.
• Never work on the electrical system while the engine is running.
• Consult a qualified automotive electrician for any concerns or uncertainties.
• This modification is not street legal in most jurisdictions. Only perform this modification on a closed track and in accordance with all applicable rules and regulations.
