AUTOOL 41CM OBD2 Extension Cable Connector for GM12pin OBD2 Adapter Wire Nylon OBDII Male to Female Extension Cord

The AUTOOL GM12 OBD2 extension adapter cable is designed to connect a GM 12-pin vehicle diagnostic interface with a compatible OBD2 16-pin diagnostic tool. It uses a pure copper core, flexible insulated outer material, and a protective nylon braided sleeve to support stable diagnostic communication and repeated workshop use. This cable is an adapter-style extension cable for vehicles with a GM 12-pin diagnostic interface and diagnostic tools that use an OBD2 16-pin connector. Confirm both connector shapes before purchase to avoid choosing the wrong cable. AUTOOL uses pure copper wiring, flexible insulated outer material, nylon braided protection, and an inspection process from injection to molding to improve durability for repeated plug-in diagnostic work. Key specifications are organized from the supplied product content and specification images. Because the listing text contains mixed wording, the connector description is kept conservative: GM 12-pin vehicle side to OBD2 16-pin diagnostic tool side. The package includes one AUTOOL GM 12-pin to OBD2 16-pin extension adapter cable. The packing list uses one product-list image only, so the buyer can quickly confirm the cable and packaging style without extra image clutter.
