O2 manifold extension for ND

Looking at the manifold options for the ND, theres catted and non catted.

Specifically in regard to the non-catted, i see comments in the items that the manifold 02 cable will need extending as it will be re-housed to behind the main cat. This is fine.
But, i cant see any for sale anywhere, or any how-tos on how other people have done this?

I saw after some looking that the NC has an off the shelf plug and play extension cable. but i cant find one for the ND?

thanks in advance

Goodwin do one but not sure how you would get it in UK
