E46 Facelift Trailer Wiring Module

[E30 325i Rag-Top 2958]

Looking for the electronic box of tricks to connect an E46 up to a trailer, has to be for a facelift car though.

I know there is a BMW one and possibly some after market versions.

Anyone got one that they don't need? I have the towbar just need to box of tricks to make the electrickery work.
