I have sold a 3-spoke steering wheel with paddles to a person with an '09 CLS and it turns out there is a problem with installation.

The airbag and paddle shifter connections are working flawlessly but the other plug for stereo/computer buttons has different shape of a plug, please see these pics:

This is the steering wheel type:



And here pics of the plugs difference:





They both have 3 pins, so logically - shouldn't it be just an easy job of swapping the plugs on the cables?

Please let me know what you think guys as I would like to avoid shipping it back and forth for refunds if it may be an easy job of a plug swap.

Thanks in advance!
