Always verify power polarity and vehicle voltage before connecting external power.

Compatibility depends on the scanner model, VCI connector, installed diagnostic software and supported vehicle database. Please confirm compatibility before ordering.
Typical Applications
- Diagnosing older vehicles with non-standard sockets
- Connecting a compatible X431 scanner to an under-hood diagnostic port
- Reading supported vehicle systems and fault codes
- Clearing supported diagnostic trouble codes

Important Compatibility Information
This adapter kit provides the required physical connection between the vehicle and a compatible diagnostic scanner. It does not add vehicle software, protocols or functions that are not already supported by the connected LAUNCH device.
A matching connector does not guarantee communication. Diagnostic access depends on the vehicle, control module, scanner model, VCI, installed software and active vehicle licence.
Identify the vehicle’s diagnostic socket visually before selecting an adapter. Never force a connector into the diagnostic port, and always confirm voltage and polarity when using an external power cable.
Package Includes
- 1 × Set of non-standard OBD1 diagnostic adapters
- 1 × Battery-clamp power cable
- 1 × Cigarette-lighter power cable
- Replacement protection fuses

Please compare your vehicle’s diagnostic socket and confirm compatibility with your LAUNCH scanner before purchase.
