Seems like as good as any place to post some complete instructions and other stuff for the E70 tow hitch (Class III). (I did the same for the E53 here (post # 55):

Please note that both the US Hitch and the Euro Hitch must be retrofit coded. The Electric Trailer Brake Kit does not require coding.
If I find anything else I'll add to this post.
