Brooks Board Replacement for PS4 Razer Panthera EVO

Hey,

New here and looking for a video on replacing the board in a Razer Panthera EVO. The board looks different as it asks for the start, options and other buttons individually.

First, the original board (screenshot) looks like all the controls are connected by the white flat cable. Was wondering if splitting is required? The buttons are also connected to a single head. Do I have to split those cables to attach the Brooks PCB? Is soldering required?
