Which one is the ground wire?
I'm installing the illuminated star on my 2012 C300. Which one is the ground wire? Prefer pictures if possible. Thanks

Also, the parking lights would be the grey wire going into the headlight correct? Splice it into there and connect it to the ground wire? For the ground wire do I splice it the same way I would the other wire?

The brown wires are the ground on MB. I post the WIS instructions for the illuminated star on these forums last year

I assume since this was posted under THIS forum, it would be at least a MY2008 or newer
