I have posted in retrofit but no-ones seems to reply there so I will post here to. I have managed to install the DIS wiper stalk and enable it with vcds. I have the washer warning as expected but I am testing the buttons and nothing is happening? Is this because the washer warning is preventing it? Secondly I know which pin 1 to ground on the back of the cluster with the blue plug however just read about it and I need repair wire? Can I not use normal wire I have laying about. Also where can I ground it? Any pics?
