This mod moves the Y endstop to the A drive, to go along with Arkeet's MGN12 mod that has the X endstop on the toolhead. This mod requires a 2 pin JST-XH to be soldered to the switch. The best way I have done it is to solder the wires to the JST-XH first, install it with a dab of super glue, then solder the wires to the Omron switch.
There are 2 different files
non pinned version
pinned version (since this mod also works with the Voron2.4_Trident_Pins_Mod)
here are a few pics for reference
you might need to bend the pins a little bit to get them to fit around the curve
