Protecting your vehicle from theft is a top priority. One vulnerability often exploited by thieves is the OBDII port. This article explores how to secure your car by removing or relocating the OBDII port and potentially using an Obdii Splitter With Power And Ground for a decoy port. This strategy can deter thieves seeking an easy target.
Understanding the OBDII Port Vulnerability
The OBDII (On-Board Diagnostics II) port, typically located under the dashboard, provides access to a vehicle’s computer system for diagnostics and repairs. However, this accessibility makes it a prime target for thieves who can use readily available tools to bypass the ignition system and steal the car. Removing or concealing the port can significantly increase security.
The image above demonstrates how easily accessible the OBDII port connector is once removed from its housing. With simple tools, a thief can gain access to the vehicle’s wiring harness.
Relocating the OBDII Port
The factory OBDII port is usually secured with simple clips, making removal straightforward. Once removed, you can relocate it to a less accessible location within the vehicle. This simple, cost-free measure can deter opportunistic thieves.
This image shows the wiring harness of a 2023 Chevrolet Camaro 1SS, illustrating the minimal number of wires connected to the OBDII port. Relocating this harness makes unauthorized access much more difficult.
The schematics provide a detailed view of the OBDII port’s wiring and pin configuration. Understanding this layout is crucial for anyone considering modifying or relocating the port.
Decoy OBDII Port with Power and Ground
To further enhance security, consider installing a decoy OBDII port with power and ground. This will make it appear functional to a thief, potentially wasting their time while you’re alerted to tampering.
You can purchase an OEM OBDII port, pins, and retainer from electronics suppliers like Mouser Electronics. Wiring this decoy port with 12V power and ground will make it appear operational to a thief’s diagnostic tool.
The retainer ensures a secure connection for the pins within the OBDII connector housing. Correct pin identification is crucial for proper functionality, whether for a legitimate connection or a decoy. Confirmed compatible pins are Molex WM3324CT-ND.
Important Safety Considerations – DO NOT Reverse Polarity
While tempting, do not rewire the decoy port with reversed polarity. This could damage legitimate diagnostic tools used by mechanics and potentially create liability issues for you.
Instead of creating a potentially damaging trap, consider using a simple cover to protect the relocated OBDII port’s pins from damage and indicate that access is restricted. This is a much safer and more responsible approach.
Conclusion
Protecting your vehicle from theft requires a proactive approach. Relocating the OBDII port and implementing a decoy OBDII splitter with power and ground can significantly deter thieves. Remember to prioritize safety and avoid any modifications that could cause harm or damage. By taking these preventative measures, you can enhance your vehicle’s security and enjoy peace of mind.
