Things have changed in OnStepX and that pinmap file isn't going to work.
I see only two changes from the MaxESP3 pinmap AUX3 and AUX4 are on different pins.
I guess you are looking to change the home sense pins for Axis1 and Axis2.
If so it's better to just use the MaxESP3 pinmap and add the following lines to Config.h:
#define AXIS1_SENSE_HOME_PIN 8
#define AXIS2_SENSE_HOME_PIN 7
