Hi Callcott,
I'm not sure what you mean by operating your ambient lighting?
The, I'll say very nice, interior ambient lighting comes on with your main headlights.
In the doors you'll find a light shining down towards the speakers.
In the tunnel console you'll see the cup holders lighted.
In front you'll see the small compartment where your 12V is lighted
Overhead, where your interior lights are, there is a small led pointed downwards shedding some light on your gear lever.
I believe that's it. And no, you cannot change the colour. Though I would have liked that very much >
