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?

The website’s posted instructions are excellent, but I have a few queries. I couldn’t find a pin-out or connection guide for the standard X1 screen to the SKR. Can I still utilize the original SD card and USB port on the printer after the upgrade? Clarifying these details would greatly assist my setup process.
