16-pin OBD2 vehicle connection cable for SD Connect C4 and compatible C5 interfaces that use the same physical main socket.
The exact plan and total amount will be shown again at the payment step.
Match the lock, pin arrangement, and vehicle-side 16-pin OBD2 end of the round multi-pin socket on your SD Connect device with the product images.
Product information
This main cable connects between compatible C5 interfaces using the same physical connection and the SD Connect C4 with the 16-pin OBD2 vehicle socket. As there is no verified Mercedes-Benz part number on the cable, no claim of original part is made.
Physical Connection Coverage
Connecting the cable, adapter, or communication module to the vehicle does not prove that the vehicle is supported by the software. The physical connector, pin layout, main device, and vehicle software must be compatible simultaneously.
Product details
Four actual product photos show the black cable body, the red-locked 16-pin OBD2 connector, and the round multi-pin device end with a blue pin seat. Close-up visuals facilitate pin comparison before ordering.
Product details
Different chassis and hardware revisions may be available under the C4 and C5 names on the market. Cable compatibility is determined by the actual socket of the interface; the model name, seller title, or device color alone is not sufficient proof.
Product details
The package includes only one 16-pin main cable. The SD Connect device, 38-pin adapter, LAN cable, computer, XENTRY software, and license are not included. The cable does not add new protocols to the vehicle or device.
Product details
The pins of the round device plug are exposed to impact during transport; it should be kept in its protective compartment when not plugged in, and the cable's weight should not be applied to the pins. The red OBD2 end is removed by gripping its body, not by pulling the cable from the vehicle. The lock and key channel are kept clean, and bent pins should not be straightened with pliers at the vehicle site.
Saving close-up photos of the device input and cable facilitates finding the same revision when selecting spare parts in the future. These maintenance steps only preserve the physical connection; they do not provide XENTRY access or vehicle support.
Product details
The SD Connect device is placed on the workbench and powered off. The key channel of the round input on the device, the color of the pin seat, the pin arrangement, and the locking mechanism are compared with the close-ups in the gallery. Since there are different chassis under the same C4 or C5 name, the housing label alone is not sufficient.
The cable plug should seat only in the correct orientation, without applying pressure; if the lock does not close, it is realigned and not forced. It is also checked that there are no bent pins or cracks on the red 16-pin connector on the vehicle side.
After physical matching is complete, device connection and vehicle identity reading are attempted on the XENTRY side; writing operations are not performed in case of unstable communication.
Product details
When using a new cable, measure the vehicle battery voltage and connect an appropriate support device if necessary. First, lock the round device end, then plug the 16-pin OBD2 end into the vehicle with the ignition off. The XENTRY interface should recognize the device, and no unexpected restarts should occur on the SD Connect.
The first test is only for vehicle recognition and control unit listing. If communication changes when the cable is moved, the connection is stopped; the round socket, red OBD2 body, and pins are inspected again.
This main cable is not sufficient on its own for older 38-pin Mercedes vehicles; the correct 38-pin adapter and vehicle and software scope must also be verified.

FAQ
Not directly. If the vehicle has a round 38-pin socket, a separate 38-pin adapter and compatible main device are required.
No. The round socket on the device side, the lock, and the pin arrangement must match the product photo exactly.
No. The product is only the physical main cable; the SD Connect device, computer, software installation, and license are not included in the sale.
No. The key channel or pin arrangement may not match. Forcing can permanently damage both the cable pins and the device socket.
No. The physical cable alone does not add DoIP support; this capability depends on the combined scope of the interface hardware, vehicle, and manufacturer software.
