This cable is used to replace the non-working Thunderbolt cable on the TB15 K16A 5T73G 05T73G dock. This cable comes with a Thunderbolt 3 plug, and it CANNOT WORK with the WD15 dock which comes with a USB-C plug. The package includes the Thunderbolt 3 replacement cable only, the TB16 or TB15 dock and other parts are not included. Cables were never used but there are some small scratches and dirty marks. Some DIY capability is needed. The cable is about 50CM.
