Unsolved Ender 6 wire Endstops in Mini 5+ Duet

[A Former User]

I have started the quest to install the Duet Mini 5+ in my Ender 6 from Creality. I have noticed that the wiring for the endstops in the Creality mainboard controller has only one cable for the Z and X and two for the Y.

I would like to know where this wires need to be installed in the new Duet3 Mini 5+. I have read the diagram and the steps to install the Mini 5+ in the Ender Pro 3, but still not clear for me, where exactly need to be connected in the new Duet Mini.

I have followed with attention the diagram in the Duet 3D website and I am aware that I need to connect the wires in one of the IO_0 - IO_6, but there is 5 options for every connector (5V_EXT, io3.out,GND, io3.in, 3.3v_EXT) but I have only one cable available for my Endstops coming for my Ender 6 wiring in the Z and X and only two for the Y.

I need your advice, my wires need to be connected to the GND in the case of the Z and X? In the case of the "Y" I have two wires, this need to be connected to the GND and the io0.in? This is the logic?.

See the example here: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+3+Mini+5++Guide+Part+1:+Wiring/87#s258

This is an ender3 and mini5+ but should be similar to the ender6
