RE: Trailer hitch retrofit (F20)
Yes I have already seen these documents.
But it does not give the contact type information for A4, A5 and A6 cables.
What I miss is just the contacts as below:

RE: Trailer hitch retrofit (F20)
I must not be clear enough sad
I already have this information.

I just miss the type of male connector to insert into the socket Z2*13B and Z2*9B.
I tried this kind of connector but it does not work sad

RE: Trailer hitch retrofit (F20)
Do you mean you are making the cable yourself rather than buying the retrofit kit?
And you can’t find the correct terminal contact?

Did you get the correct terminal contact? In the installation instruction it stated 2.50mm2.

RE: Trailer hitch retrofit (F20)
Yes, that's exactly it.
I do not use the retrofit kit, I make the cable myself.
And actually I can not find the contact terminal for the Z2*13B connector.
I will try with the reference: 12520007253
I'll keep you informed.
Thank you

RE: Trailer hitch retrofit (F20)
I ordered all the material to make the assembly.
However, I have a technical question.
In the BMW installation guide it says :

"Only cars wihtout the High fuse box already installed at the rear.
If the contacts on PIN4 and PIN5 of plug Z2*9B are missing, the rear fuse holder must be replaced and additional cable V connected."

My question is simple, how do I know if I need to wire the "V" cable?
For information, I don't have the default connector Z2*9B in my rear fuse box..
