The Jaltest JDC622A connects the 4-pin connector of the Weber engine to the 16-pin OBD2 port of your Jaltest diagnostic cable. On the engine side there is a black connector with a green sealing ring, four black wire sleeves and a locking bracket at the side; on the interface side the OBD2 connector sits on a black plastic module. The cable measures 28 to 30 cm.
Behind this connection lies one control unit: The ECM of the Weber MPE-750. With it you read fault codes and measured values, follow the values live, and set parameters and calibration. The same control unit is found in the coverage for the HSR-Benelli Hydrospace S4. The product page lists only the Jaltest Link V8.1 for this cable. The cable falls under Jaltest Marine.
