I choosed GM-Number: 13393847 which is a seatpad heater (4 wires).
I recieved a totally different backrest heater with Nr. 13451993 (2wires).
I get an answer from customer service, that the Opel factory changed the part number. I hope they will offer a solution (sending the right part / refund or something). Currently the situation is very disappointing.
