Powerfold retrofit
 

Hi everyone I’m new to this so please bare with me!
I have a 2007 bmw e60 523ise and would like to retrofit powerfold door mirrors, I have bought the switch cluster which operates both the mirrors and the rear electric blind which I intend to fit another time, anyway, other than the mirrors and switch gear do I need anything else? My car has electric front seats with the drivers seat having the memory function. Thanks guys. Kindest regards Steve
