Hi I have a 2007 1.9tdi with the heated seats switches in but the loom was not fitted. Can anyone send me a diagram/show where the three wires are meant to go they are all white, look identical and all the same thickness. The loom is from a company called Kufatec it came with the car when I bought it but no instructions 🙈. I’ve contacted Kufatec and no response.
