For every-one's information the reversing light wire to splice into is SW/BL as in Black & Blue! Even local mate at VW dealer said it was Grey/White as per their factory diagrams.Have now fitted laserline parking sensors and have to say 'stunning' as close to factory as you will find!Mind you I worked on Concorde and in F1 so needless to say, requires a little bit of skill Drilling 18mm holes in a painted bumper and fitting from behind with near flush fit and no security of a 'horrible' flange to cover/hide hole takes a lot of nerve. I recommend Valium before hand, I managed without but was a bit of a wreck truth be told.Pics to follow and of carbon wrapping!!
