Which steering wheel control lead?

[MRBILLYUK]

I've just bought this Sony mex n7300bd. It's for my Clio 182. I don't know if that makes a difference?
I want to keep the steering wheel controls.
Which lead do I need and where from?
Any help greatly appreciated.

Anybody?
Is this the only lead I need to connect a Sony head unit to keep the steering wheel controls?
