Outdated

!!! if you are unsure, you better keep your fingers off this change! Your motherboard may be damaged in some circumstances !!!

1. you have to cut the nose off of the connector "LCD", because you have to install it in the other direction to the SKR 1.3 "EXP1" connector.
2. The wire for +5V (Pin2) and the wire for GND (Pin1) at the LCD connector have to be swapped. (Keep in mind, this is the critical Part!)
3. The "CLK Signal" (Pin9) at the LCD connector has to be rewired to (Pin7) at the LCD Connector. After the modification (Pin9) has to be open, because on SKR 1.3 Mainboard this pin is open drain
4. The reset switch at the Display is wired to (Pin7) at connector "J3" at the display. You only neet a single wire to connect (Pin7) at "J3" from the display to (Pin3) at "EXP2" at the Mainboard.

Here is the LCD Connector of ANET_FULL_GRAPHICS_LCD before and after the modification.
