hi

going to buy a stereo for my vectra c 2007.

ordered this lead to connect it

but not sure which lead i need for steering control connectivity?

do i need the lead i have ordered and another patch lead or a different thing altogether?

havent bought the stereo yet so does it differ between brands? if it is easier or cheaper to get one for a certain brand i will buy that brand!

cheers
