The repair wire is listed above in the diagram - 000 979 025. It is a small (12") long wire with the correct terminal that is required at the Cent Con Module on each end.
You will have to run a wire from behind each headlight (spliced to the extra wire at the adaptor), through the bulkhead behind the battery, and behind the dash to the CCM, then splice the wires to the repair wire cut in two.
I removed the plugs from the CCM and this will allow you to push the new terminals into the correct hole in the plug, refit the plugs and all is good.
Some coding to tell the car it now has Bi-Xenons fitted, and ll should be good.
