Hi, My current seats are cloth with lumbar support and the leather seats that I have bought to fit have the lumbar support with heated seats... Can someone clearly explain what I will need to buy/do to get the heated seats working? I assume I would have to get this KUFATEC GmbH & Co. KG - Kabelsatz Sitzheizung Audi A4 B7 33856 loom from Kufatec and fit it to my vehicle and then would it start working? OR is this loom not needed? A DIY guide would be appreciated! I would very much appreciate your input/help!! P.S: I am removing the leather seats from a Donner car!
