From your measurements, it sounds to me that the Duet Y endstop connector is working correctly. You have configured the endstops as active high, which means that the red LEDs on the Duet should be lit when the endstop switch is connected but not triggered.
So I think the problem is that you have not connected the endstop switches correctly. From your photos, and confirming with a schematic I found elsewhere, I believe the correct connection is as follows:
Endstop Pin 1 (as indicated by the figure '1' on the PCB in your first photo) - connect to STP on the Duet endstop connector
Pin 2 or pin 3 - connect one of these to GND on the Duet endstop connector
Pin 4 - connect to 3V3 on the Duet endstop connector
You will need to use S0 in your M574 command, because these endstops are designed to produce active low outputs.
Please try this connection scheme with either the X or the Z endstop connector. If it works, then try it with the Y endstop connector too.
Also make sure that there is nothing metallic underneath the endstop boards that could be shorting connections together.
