ST170 rear brake conversion

[Londontuning]

Hi Guys
I am new to Ford, so please excuse my ignorance.
I am converting my 2007 Transit Connect T230 L to a petrol using a 2004 ST 170 donor which I purscaxed as s complete car.
I have looked into this and am aware that I use the engine and complete wiring loom for the conversion.
My question is to do with brakes.
As I plan on keeping the ST 4 stud setup, I was wondering what handbrake cables I need for the conversion?
As I have the complete vehicle it only seems logical.
Thanks for your help
