Hello i have an A4 B7 avant in which i've put in some S-line seats because the heating element in the old seats didnt work. in the new seats there is electric lumbar support and the car itself didn't come with this from the factory.
is it possible to just connect the wires to a positive lead and ground. And make the lumbar support work?
It looks like the motor is under the seat itself so, wouldn't it in theory be possible to connect it to fx. the cigarette lighter positive wire?
Thanks in advance
