16-Pin OBD2 Extension Cable for Launch X431, ThinkDiag, Autel and ELM327

16-Pin OBD2 Male-to-Female Extension Cable

The OBD2 Extension Cable provides a flexible connection between a vehicle’s 16-pin diagnostic port and a compatible OBD2 scanner, diagnostic interface or code reader.

It is useful when the vehicle’s OBD2 socket is located in a tight or inconvenient position. The extension cable allows the diagnostic device to be positioned safely away from the dashboard and helps reduce repeated stress on the vehicle’s original diagnostic connector.

Main Features

• Standard 16-pin OBD2 male-to-female design
• Extends the vehicle’s diagnostic connection
• Flexible flat cable for easier routing
• Provides easier access to difficult OBD2 port locations
• Helps reduce physical stress on the vehicle’s diagnostic socket
• Protects compact diagnostic adapters from accidental impact
• Suitable for workshops, mobile technicians and personal use
• Simple plug-and-play connection
• No software or driver installation required

Compatible Diagnostic Devices

The cable can be used with many diagnostic devices equipped with a standard 16-pin OBD2 connector, including compatible models from:

• Launch X431
• ThinkDiag
• ThinkCar
• Autel
• Xtool
• ELM327
• Vgate
• OBDLink
• Generic OBD2 scanners
• Bluetooth and WiFi OBD2 adapters
• Wired diagnostic interfaces
• Other compatible 16-pin diagnostic tools

Compatibility depends on the scanner’s connector design, required communication pins and the vehicle’s diagnostic system.

Common Uses

• Extending the vehicle’s OBD2 diagnostic port
• Connecting a scanner when space below the dashboard is limited
• Moving Bluetooth or WiFi adapters away from surrounding trim
• Reducing strain on the original vehicle connector
• Keeping a diagnostic interface accessible during road testing
• Preventing large scanners from interfering with the driver’s legs
• Providing easier access during workshop diagnostic procedures

How to Use

1. Turn the vehicle ignition off.
2. Connect the male end of the extension cable to the vehicle’s OBD2 port.
3. Connect the diagnostic scanner to the female end of the cable.
4. Confirm that both connectors are inserted securely.
5. Turn the ignition on and start the diagnostic application.
6. Disconnect the cable after completing the diagnostic procedure.

Important Notes

• This product is an extension cable only and does not perform diagnostics by itself.
• A compatible scanner and diagnostic software are required.
• Confirm that the connected equipment uses a standard 16-pin OBD2 connector.
• Compatibility with specialised programming interfaces should be confirmed before use.
• Do not use the cable if its connector, pins or insulation are damaged.
• Keep the cable away from pedals, steering components and other moving parts.
• Do not pull the cable when disconnecting it; hold the connector housing instead.
• Remove the cable when it is not required to avoid unnecessary battery consumption from a connected diagnostic device.
• Communication and programming reliability depend on the connected equipment, vehicle and cable condition.
• For sensitive ECU programming operations, use only equipment and connections approved for the selected tool.
