Moin, moin, I have no idea at all and I’ve got your help. I bought an AHK from Rameder and had it installed at Ford. Now I got a bicycle carrier from my neighbor, plugs see picture 2. The plug from my AHK can be seen on pictures 1 and 3. Somehow this doesn’t fit. What do I have to do? Can I buy an adapter? Can this be that the plug from the AHK is not right??? Please send me any feedback!!! Thank you in advance! vo gstone
