Hi

Today i install a used trailer hitch to my s211 (2005) E class.
The only probleme is that the plug (to connrct to the fuse box) is missing

I want to ask if enyone have the wiring diagram for this model.

Thanks

I find all original wires. The installation is ready now
I want to ask if enyone know how to code it with mob star.

Thanks

I ask how can I code it with mb star.
The control unit has to know that I install a trailer.
How can I do that.
All the parts I use is original

Looks like you are in Europe with this electric hitch?
Would you mind to share the wiring pictures?
I want to put hitch on my wagon, but in US they are very rare.

AHE is the trailer control unit.
I have to do something?

Being in the US, and able to obtain the harness and module, would it be worth it to make this work? I'm wanting to minimize hacking. How does this wire harness connect to an trailer socket (perhaps it's different between US/North America and elsewhere)?

NOTE: Just wanting to be as safe as possible should I bother with a lightweight trailer. I have a truck and trailer with four-wheel electric brakes and KNOW that trailer brakes are a good thing!
