Compatibility And Fitment

Compatibility And Fitment

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.

GM 12-Pin Vehicle Side

Use this cable only when the vehicle diagnostic port matches the GM 12-pin style shown in the product images.

OBD2 16-Pin Tool Side

The tool side is made for compatible diagnostic tools with a 16-pin OBD2 socket or connector interface.

Verify Before Purchase

Do not rely only on vehicle year or brand name. Compare the actual port shape and pin layout with the product image before ordering.

Key Features

Key Features

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.

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.

Before You Order And Use

Before You Order And Use

This is a connector-specific diagnostic cable. Check the connector type carefully before ordering and avoid forcing the cable into an unmatched port.

Confirm GM 12-Pin Port

Make sure your vehicle uses the GM 12-pin diagnostic interface shown in the product images.

Confirm OBD2 16-Pin Tool Side

Use this cable with compatible diagnostic tools that match the OBD2 16-pin connection side.

Do Not Force Insertion

If the connector does not align smoothly, stop and recheck the port shape and pin layout before use.

Adapter Cable Only

This product is an extension adapter cable. It does not perform diagnostics by itself and must be used with a compatible diagnostic tool.

Use Under Proper Handling

Avoid excessive pulling, crushing, twisting, or bending near the connector ends to preserve cable life.

Length Reference

The specification image shows 410mm / 41cm / 16.14in. Use this value as the practical cable length reference.
