I had already informed admin amd King a while ago that King's article was misleading and could create a short circuit on the X5s electrics.Although he changed it ,its still wrong!

Both the Yellow/ white and the purple/ white connections are positive(+) going into pins 85 and 86 on the relay!There is no GROUND(-) GOING to the relay ,so how does the camera work?

He should have a brown wire(-) going to pin 85 and the Yellow/white (+) to
pin 86 .The purple/white wire should not be used at all!!!!
Both the brown wire and the yellow/white wire are on the plug connecting to your reversing light.
