Vehicle theft is a persistent concern for car owners. With modern vehicles increasingly reliant on electronic systems, the On-Board Diagnostics II (OBD2) port has become a common entry point for thieves. This port, designed for diagnostic and repair purposes, can unfortunately be exploited for unauthorized access to your car’s systems. One straightforward, cost-free method to deter OBD2-based theft is to remove or relocate your OBD2 connector. This guide, brought to you by the automotive experts at obd-de.com, will walk you through the process of Obd2 Connector Pin Removal, enhancing your vehicle’s security.
Understanding the OBD2 Port and Its Vulnerability
The OBD2 port is typically located beneath the dashboard on the driver’s side of most vehicles. It’s designed to provide mechanics and technicians with access to vehicle data for diagnostics and repairs. However, this accessibility also makes it vulnerable to theft. Thieves can use readily available tools connected to the OBD2 port to bypass immobilizers, program new keys, or disable security systems, all within a matter of minutes. By making this port less accessible, you can significantly increase the time and effort required for thieves, potentially deterring them from targeting your vehicle.
Step-by-Step Guide to OBD2 Connector Removal
Removing the OBD2 connector is a simple process that requires no special tools and can be done in minutes. Here’s how:
1. Locating the OBD2 Port:
First, locate the OBD2 port in your vehicle. Consult your owner’s manual if needed, but it’s usually found under the dashboard on the driver’s side.
2. Disconnecting the Connector:
The OBD2 port is held in place by clips on either side. From the cabin side, reach up behind the port and feel for these clips. Usually, you can depress these clips with your fingers. In some cases, a small flathead screwdriver might be helpful to gently push the clips.

Once the clips are depressed, gently push the OBD2 port from the front (cabin side) and it will detach from its housing, allowing you to access the wiring harness behind it.
3. Accessing the Pins:
With the OBD2 port removed, you will see the wiring harness and the back of the connector. You can now choose to simply let the OBD2 port hang loose, hide it, or proceed with further modifications.

The image above shows a typical OBD2 connector wiring configuration. While you could de-pin individual wires, for basic security purposes, simply removing or hiding the entire connector is often sufficient and simpler than individual OBD2 connector pin removal.
Enhancing Security: Hiding or Creating a Dummy Port
Once the OBD2 port is detached, you have several options to enhance your vehicle’s security:
- Hiding the Port: The simplest approach is to tuck the disconnected OBD2 port and wiring harness up behind the dashboard, making it difficult for thieves to locate quickly. This free and reversible method can be surprisingly effective.
- Creating a Dummy Port: For added deterrence, consider installing a fake OBD2 port in the original location. A thief expecting a quick OBD2 port access point might be deterred upon finding a non-functional port. You can purchase OEM OBD2 ports and components from suppliers like Mouser Electronics (part number WM3324CT-ND https://www.mouser.com/ProductDetail/Molex/0504208000).

You can even wire the dummy port with 12V and ground to give the appearance of functionality, potentially further confusing thieves.
Important Warning: Avoid Reverse Polarity Wiring
While considering security measures, it’s crucial to AVOID any temptation to rewire the OBD2 port with reverse polarity. Doing so can severely damage any diagnostic tools connected to it, potentially including those used by legitimate mechanics. This could lead to legal liabilities and is strongly discouraged. Instead, focus on non-destructive deterrents like hiding the port or using a dummy connector.
Conclusion
Removing or hiding your OBD2 connector is a straightforward and effective step in enhancing your vehicle’s security against theft. While it may not be a foolproof solution, it adds a layer of protection that can deter opportunistic thieves. By understanding OBD2 connector pin removal and implementing these simple security measures, you can take proactive steps to protect your vehicle.
