I know this is off-topic for this board, but I have hardwired a V1 on my M5 and I want to do the same on my x5. The panel with the sunroof switch and map lights is a little different than the M. Does anyone know how it comes off? Other than that is the procedure the same as with the M? I can't remember exactly which wire is the one to splice in, white with green stripe? Thanks for any help.
