New pads (not upgrade) question

I want to buy some different pads for my 1K and was wondering if installation was just removing the case and swapping pads. Do I have to mess with the sensors or is it just a matter of laying the pads over them? Thanks fellas...

If you already have the new pad senser set installed, it loks can just switch out easy with any of the available colors

The new style pads use a rubber mat in a 4x4 grid, instead of individual sensors/rubber pads.
