Connecting Anet 8 2004 display with Ramps 1.4 to Aux2 can't seem to figure it out I've heard about switching out some connectors, but can't seem to figure out which ones and can't seem to find a diagram out there that is much help. Does anyone know which connectors I should switch to achieve this?
This answer clearly describes that you need to switch pins 1 and 2. It also describes that the MKS board is similar to a RAMPS board. 

First thing to look for is the layout of the AUX2 header:



The pin layout reveals that pin 1 is VCC and pin 2 is GND. These need to be switched to be able to connect the display on AUX2.
