Can anyone tell me the function of this switch..I am in the middle of doing a M6 to A4 conversion and this is the only thing that is left for4 me to do..The Pcm already has a wire and it is the right color in it..Does this mean that my car is already wired up for this switch even though it is a M6 car originally? There were two other wires that changed function when the PCM got reflashed but this one does not have another function in either Manual or auto..Can anyone help? One other thing..What is the function of the Extented brake travel switch do?
