I'm about to do the fog light within the existing brake lights mod.

So that is the two inners act as a fog when switched on from the cabin and stay on.

Conversely when the switch is off all four act as brake lights.

In my case, all four lights act as a brake light.

So can some more proficient of you or those who have done this check my image below at what my understanding is and/or elaborate on what needs doing?
