OBD2 extension cable OEM OBD2-EXT-1-2 One-to-Two 16-pin cable, male-to-female splitter

OEM OBD2-EXT-1-2 One-to-Two 16-pin cable is an OBD2 extension cable that splits a single standard 16-pin diagnostic port into two outputs. The male-to-female splitter design allows two devices or scanners to be connected simultaneously to the vehicle's OBD2 socket without the need for rewiring or permanent modification. The cable is intended to maintain all necessary signal lines for diagnostics, programming and monitoring tools while providing convenient access for workshops and home mechanics.

Advantages

The OBD2 extension cable provides simultaneous access to a vehicle’s OBD2 port for two devices, enabling parallel diagnostics or monitoring. Its male-to-female connector arrangement preserves the original connector orientation and simplifies quick connection and disconnection of tools. The cable reduces the need to swap devices during testing, speeding up workflows in service environments and for DIY projects. Designed for compatibility with standard 16-pin OBD2 sockets, it eliminates intrusive changes to the vehicle wiring.

Suitable for

• Connecting two diagnostic scanners at the same time
• Simultaneous data logging and live monitoring
• Workshops performing parallel programming and testing
• DIY mechanics needing concurrent connections for troubleshooting

Key specifications

• Connector type: standard 16-pin OBD2 male to two 16-pin OBD2 female outputs
• Cable function: one-to-two splitter/extension for diagnostic signals and power
• Compatibility: conforms to standard OBD2 16-pin pinout used in modern vehicles
• Use case: supports diagnostics, programming, monitoring and data logging tools
• Physical design: inline splitter with durable molded connectors for repeated use

How to use

Plug the male 16-pin connector of the OBD2 extension into the vehicle’s OBD2 diagnostic socket. Connect up to two diagnostic devices or scanners to the female 16-pin outputs. Ensure both devices are powered off when making connections, then power them on and start the diagnostic or monitoring software as required. After use, disconnect devices and remove the extension from the vehicle if long-term attachment is not needed.

Usage recommendations

Use the extension cable on vehicles with standard 16-pin OBD2 sockets and verify device compatibility before connecting two tools simultaneously. Avoid using the splitter to power high-current accessories not intended for the diagnostic port. Keep connectors clean and dry and store the cable in a protected place when not in use to maintain connector integrity.
