My query regards correct wiring of the Resler which is supplied with solid white, solid brown, solid red and solid violet tails. My vehicle's iBus plug for the original BMW CDC has three connecting wires - one solid brown, one red/white stripped and one white/yellow stripped. I guess the brown in either case is Ground but I am unsure about the other wires (i.e. does white/yellow and red/white equal solid white and solid red respectively as far as the Resler is concerned) - have not a clue what the purple Resler wire if for!
Can anyone advise please?
