Which models have illuminated steering buttons

Hi all. I am doing an retro fitting illuminated steering wheel buttons into my VZ Berlina. I have bought a VZ Calais clock Spring and wheel but still they don't light up. Seems the Berlina and Calais have a different loom at the clock Spring; even though I have been told they are the same. So now I will need to cut one from a donor car. I know SV6 with paddle shift have light up. But I need to know for sure what other models have the light up buttons. I have been told several times Berlina and higher have it. Which is doesn't.

So if your VZ buttons light up can you please tell me the model.
