Hello, but the pin I think should not be connected directly to the fuse terminal, I think it has to be connected to the BCM (body control module) of the car, otherwise it would be working all the time I suppose I have not tried, also they reach high temperatures and in Summer can be a problem ... if you connect to the BCM you would control at what temperature you want them to turn on, for example when the temperature is low as 4ºC the car decides that they should be heated before possible ice. I have seen in retrofits of other vag cars that connect the BCM in the connector "B" on pin number 9, but it turns out that the pole is already occupied, here is my question that if there will be another pin where to connect it. if someone knows or wants to retrofit out of curiosity.
