Board connectors

I’m working on my enclosure and want to move the electronics to the outside of the box. Are the connectors used on the 2.4d board still Molex KK as they were in this post from 2015? Its only 10 pin now since they took away the kill-switch pins. What are the connectors for the steppers? Also, why is there a 5th connector sized for the stepper connectors on the board?
