Hello I bought and replaced an SL 500 R230 Built 09/2004 with 7G transmission and me an AMG steering wheel with shift paddles. My old steering wheel was heated.It went a cable from the dashboard to the steering wheel behind the airbag where a small box sits. From the box run the cables into the steering wheelheitzung … that was the old stand. Now I mounted the AMG steering wheel and had to notice that the cables from the shift paddles do not fit into the small box, so I researched.. the d I could now weave it from an accident SL 55 and would like to build it up next week. my question does that work at all? Is the supply line to the box also for the seesaws to use so a bus cable or just a power supply? Did anyone ever try this? would be great if someone could help me further
