Sidewinder X1 SKR V1.3 Upgrader questions

The instructions that have been posted on web site are fantastic. There are a few questions I have. I cant see a pin-out or connection to the skr for the standard screen on X1. Can i still use the existing SD and usb port on printer when upgraded?

I’m sure ill have more questions. I’ve upgraded many printers but this is a favour for a friend.

Many thanks

Also the other instructions for the likes of the 1.4 upgrade say to remove pins on the tcm2209 is that the same for the v1.3?
