W164 ML towing socket wiring diagram

[Mark A]

I am going to replace the existing 13 pin towing socket on the wife’s ML.

It is an OEM MB towbar but it looks as if some of the wires have come away from the socket and I want to make sure everything gets wired up in the right place. Does anyone know what each of the different wire colours correspond to??

Tried that first - I can get universal colour vs pin allocation chart but my wire colours don’t match.

Does the wiring at the tow socket match the wiring at each tail light?

Will have a look- ta. if not it looks as if I will have to get the multimeter out.

Hi iam in the caravan industry and there is 2 types of cable for 13 pin plugs with slightly different colours .if you go to british caravans club site it shows the difference in the colours and the pin numbers they go on .other option is to test each one to find what it does .I think they are pins 11 black white 12 blue white 13 red white .have no workshop in today but can ask Monday if still stuck.
