How should the limit switches on the X and Y axis be connected correctly?

[Pavelev]

I have it set as in those photos except // # define USE_YMAX_PLUG I don't know what it's for. End Stop is not functional. I also tried false and true. Even if I disconnect the End Stop, the axes will start. When the printer is turned on, it reports Failed to enable Bed Leveling.DSC00275.jpgAttachment 16879
