Key Features
Braided Protection for a 41 cm GM Connection
Pure Copper Core
The inner wire uses a pure copper core to help support stable diagnostic signal transmission and reliable tool communication.
Flexible Insulated Outer Layer
The outer layer uses flexible TPE / TPT-style material described for insulation, flexibility, and everyday workshop handling.
Nylon Braided Sleeve
The protective nylon braided sleeve adds wear resistance and helps protect the cable from pulling, bending, and daily use.
8-Step Inspection Process
AUTOOL applies a production and inspection process from injection to molding to help ensure stable cable quality.
Frequent Plugging Design
The cable is designed for more than 10,000 plug-in uses under proper handling, making it suitable for repeated diagnostic connection work.
Compact 410mm Length
The 410mm / 41cm length gives extra working reach without creating excessive cable bulk around the diagnostic port.
Nylon-Braided Exterior
The protective sleeve resists wear from pulling, bending and repeated workshop handling, with an approximately 125g cable build.
GM 12-Pin to OBD2 Connection
Use this pure-copper-core adapter only when the vehicle has the GM 12-pin diagnostic interface shown and the connected tool has a compatible 16-pin OBD2 port.
Length Reference
410mm / 41cm / 16.14in. Use this value as the practical cable length reference.
Passive Adapter Connection
Routes the stated legacy connector pins to a compatible 16-pin diagnostic tool; the adapter adds no scan functions or protocol conversion.
Connection and Fit Notes
Avoid excessive pulling, crushing, twisting, or bending near the connector ends to preserve cable life.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
How to Use
Connect, Route and Check Communication
Confirm The Vehicle Port
Identify the exact vehicle connector, year, and pinout; inspect it for damage.
Confirm The Tool Chain
Match the scanner, software, protocol, target module, and required authorization to the GM vehicle before connecting the adapter.
Connect Safely
Follow the vehicle and tool procedure, align connectors correctly, and never force a mismatched plug.
Route Without Strain
Position the cable away from pedals, sharp edges, heat, moving parts, and pinched trim.
Verify Communication
Run the intended read-only connection check first. If communication changes, remove added devices or the extension and compare direct connection.
Safety & Compatibility
Check Pin Fit, Routing and Power Limits
Cable Function
Use the cable for physical connection and routing; protocol and diagnostic functions come from the vehicle and connected tool.
Match the Pinout and Tool
Match the connector and pin routing to the vehicle and diagnostic tool.
Vehicle Movement
Keep all cable and device parts clear of pedals, steering, seat tracks, doors, and driving controls.
Electrical Load
Do not attach unknown or high-current devices to vehicle diagnostic power. Follow the vehicle and tool current limits.
Disconnect If Unstable
If a tool drops connection, overheats, resets, or changes vehicle behavior, stop and return to a known direct connection.

FAQs
Connector, Fit and Function Questions
What Vehicle Connector Is This Cable For?
This cable is for a GM 12-pin vehicle diagnostic interface. Before ordering, compare your vehicle diagnostic port with the GM 12-pin connector shown in the product images.
What Diagnostic Tool Connector Does It Match?
The tool side is made for compatible diagnostic tools using an OBD2 16-pin connector interface. Confirm your scanner or diagnostic cable side before purchase.
Is This A Universal OBD2 Extension Cable?
No. This is a GM 12-pin to OBD2 16-pin adapter-style extension cable. It should not be treated as a universal standard 16-pin to 16-pin OBD2 extension cable.
How Long Is The Cable?
The specification image shows a 410mm cable length, about 41cm or 16.14in.
What Materials Are Used?
The cable uses a pure copper core, flexible insulated TPE / TPT-style outer material, and a protective nylon braided sleeve. These materials are used to improve signal stability, flexibility, and durability.
What Is Included In The Package?
The package includes 1 AUTOOL GM 12 Pin To OBD2 16 Pin Extension Adapter Cable and the retail package bag shown in the product-list image. Diagnostic scanners, vehicles, and other test equipment are not included.
Can I Force The Cable If It Does Not Fit Smoothly?
No. If the connector does not fit smoothly, stop using it and recheck the connector shape and pin layout. Forcing the cable may damage the vehicle port, diagnostic tool connector, or cable pins.
Does This Cable Add Diagnostic Functions?
Use the adapter for physical reach and connector routing. Available functions depend on the vehicle pinout, scanner, software, protocol, and authorization.
Does The Adapter Convert The Vehicle Protocol?
The adapter routes the legacy GM connector to a 16-pin tool connection. Match the connected tool to the vehicle, protocol, module, and task.
