OBD II extension cable PCI-681 60 cm — diagnostic port extension lead

OBD II extension cable PCI-681 60 cm — diagnostic port extension lead provides a straightforward way to extend the vehicle OBD II diagnostic connector by 60 cm. This extension lead creates additional reach between the vehicle’s diagnostic port and scan tools, adapters or other diagnostic devices, reducing strain on the original socket and allowing more convenient access in workshops or field conditions.

Advantages

The extension lead maintains a compact and flexible connection while preserving signal integrity between the diagnostic tool and the vehicle ECU. Its 60 cm length gives sufficient clearance to position a scanner or adapter outside tight cabin spaces, and the cable is designed for repeated plug/unplug cycles to support routine diagnostics and troubleshooting. Using this extension reduces wear on the vehicle’s factory connector and simplifies connecting third‑party devices.

Suitable for

• Connecting OBD II scanners and code readers where direct access to the vehicle port is limited
• Workshop and garage diagnostics that require placing tools on a workbench or cart
• Mobile service and field repairs where technicians need extra reach from the port
• Connecting adapters or dongles that remain connected during extended testing or software updates

Key specifications

• Connector type: Standard OBD II male-to-female extension
• Cable length: 60 cm
• Compatibility: Vehicles with a standard OBD II diagnostic port
• Cable construction: Flexible insulated conductors for repeated use
• Operating purpose: Diagnostic signal extension for scan tools and adapters

How to use

Align the male end of the extension cable with the vehicle’s OBD II diagnostic socket and insert it firmly until fully seated. Connect the diagnostic tool or adapter to the female end of the extension cable. Ensure connectors are fully inserted to maintain proper electrical contact. After diagnostics are complete, disconnect the diagnostic device first, then remove the extension from the vehicle port to avoid stress on connectors.

Usage recommendations

For reliable operation, avoid excessive bending or kinking of the cable near the connectors and keep the connector contacts free from dirt and moisture. Use the extension in environments and vehicles with a standard OBD II interface, and store the cable coiled without sharp folds when not in use.
