In simple terms, the GODIAG Full Protocol OBD2 Jumper is a specialized cable interface that allows you to connect a car's computer—known as the ECU (Engine Control Unit)—directly to your programming tools on a workbench, without needing the ECU to be inside the vehicle.

This cable acts as a "universal bridge." It provides the necessary power and data connections to the ECU so you can perform "Bench Mode" operations like cloning, chip tuning, or advanced diagnostics.

What is this cable used for?

• Bench Programming: It allows you to read and write ECU data while the module is out of the car.

• Stable Power Supply: It connects to a 12V/24V power adapter to safely wake up the ECU for communication.

• Protocol Support: It carries all major communication signals, including CAN-High, CAN-Low, K-Line, and L-Line.

• Safety First: It features built-in protection to prevent short circuits, ensuring your expensive ECU remains safe during the connection process.

What type of devices can it be used with?

This jumper is compatible with almost all professional ECU programming and tuning tools, including:

• MPM / PCMTuner: Ideal for GM vehicle tuning.

• KESS V2 / KTAG / KESS3: Used for remapping and firmware updates.

• FGTECH / MPPS: Common for European and Asian ECU reading.

• BYSHUT / DISPROG: For specialized locksmith and technician tasks.

What type of pins does it attach to?

The cable set is designed to be universal and includes various connectors to fit almost any ECU pin layout:

• Standard OBD2 Port: To plug in your diagnostic or programming device.

• Multi-Sized Jumper Leads: The kit includes several sizes of female connectors (e.g., 1.0mm, 1.5mm, 2.0mm) that slide directly onto the metal pins of the ECU.

• Color-Coded Wires: Each wire is color-coded according to international standards (e.g., Red for Power, Black for Ground, Blue/Yellow for CAN) to make the connection process easy to understand.
