Sorry for my bad english, because i'm dutch. I'm doing a retrofit of an rns-e in my audi s3 8l 2002 and my car didnt have nothing of any radio inside when its build. So i don't have any k-line wire already there. Tomorrow i will put my car/navigation on a vagcom for to install my rns-e My question is: What color of wire or pinnumber is my k-line at my obd plug of my car? I have there the next wires: - 2 brown wires - 1 red/white - 1 green/black - 1 grey/white Thanks for your help!
