Where are the controls for heated seat located on a Connect?

[coffee_king]

I'm currently looking at buying a newer shape (Approx 2017) Transit Connect and you know what some dealers are like, they don't list all the specs because they don't even know them. So I'm usually having to go by photos they have posted online to check specs.
Can anyone tell me where are the controls for the heated seat located on a Transit Connect please as this is an optional extra I'd love to have?
Thanks in advance.
