I've done a major fuck up... I spend 1000 GBP on a set of Performance Alcantara Sport seats for my BMW. Mine now is heated and the new one is as well.... Not working after swap.

My issue is that the lumbar support, which is why I bought the seats, does not work, just as the heat.. Anyone ever tried to upgrade seats to performance or sport seats? Need to know some wiring.

My car is a 2012 F20 118d with basic seats and heat.

REALLY WANT THIS TO WORK! Love my car, but miss some comfort and the greater look
