Mazda2 Cruise Control

Hi I was looking to install cruise control into my 2011 Mazda2 Neo DE petrol (auto) and just wondering what parts I'd have to buy to do this or how to find out which parts I'll need.
 
@murch is the brake switch for the brake pedal? Is there additional wiring that’s needed or is it already in the loom? I have just stumbled across this today so am just staring to work out what’s needed. Have ordered a steering wheel so am now trying to sort out the rest.

I have a 2008 DE Genki manual. Also have a 2018 CX-9 and have had a MX-5 in the past.
