Wooden steering wheel

Hello

I'd like to ask you a question. I bought a wooden steering wheel from an A6 4B for my A8 D2 year 2000. On numerous pictures in the net I have seen this steering wheel already installed in the A8 D2! When I wanted to install the new wooden steering wheel today, I noticed that some connectors are installed on the old series leather steering wheel. The yellow plug is the same with both steering wheels, with the new one two plugs are additionally installed. Both plugs depart from the yellow plug (a brown and a white one ) supposedly these should be from the steering wheel heater and the horn. At the wooden steering wheel two cables ( violet and green) go away from the yellow plug to the button for the horn as I mean. Has someone got a tip for me how to get the wooden steering wheel mounted so that the horn etc. works. ( by the way, the original steering wheel had no shift paddles )

Greetings Thomas
