This is a single OBD1 to OBD2 adapter cable designed specifically for General Motors vehicles. It bridges the gap between older OBD1 systems and modern OBD2 diagnostic tools.
The cable features a 12-pin male connector on one end for the vehicle and a 16-pin female OBD2 port on the other end for your scanner, code reader, or other diagnostic device.
Installation is straightforward. Ensure the vehicle is off, connect the adapter to the car's diagnostic port usually located under the dashboard, and then connect your OBD2 tool.
By using this extension cable, you protect the vehicle's factory port from potential damage and make it easier to reach the port in tight spaces during diagnostics.
Please note this is a passive adapter cable. It requires a separate OBD2 compliant scan tool to function. It is not a scanner itself and does not read codes independently.
