AUTOOL 41CM OBD2 Extension Cable Connector for GM 12 pin to 16pin OBD2 Adapter

The AUTOOL GM 12 pin to 16 pin OBD2 adapter cable is designed to connect compatible GM 12-pin diagnostic ports with 16-pin OBD2 diagnostic equipment. It helps extend the diagnostic connection, reduce port strain, and support more convenient scan tool operation during vehicle maintenance. This adapter cable is useful when the vehicle diagnostic socket and the diagnostic tool use different connector formats. Please confirm the vehicle-side port shape and pin layout before purchase. The cable combines a short 410mm extension, reinforced outer material, copper wire core, and compact connector design for workshop and personal diagnostic use. Check the cable length, weight, material, connector size, and diagnostic interface compatibility before ordering. Use the cable only after confirming that the vehicle diagnostic port and diagnostic tool connector match the adapter. The package image shows the AUTOOL adapter cable and protective package. No diagnostic scanner is included. This is a physical adapter cable. Diagnostic success still depends on the vehicle, diagnostic tool, and supported communication protocol.
