Your problem is pin 3.
The LED on pin 3 is the illumination LED.
The LED on pin 5 is the indicator that is active with the latching relay.
It sounds to me like your illumination/dim “power” on pin 3 is + instead of ground (must be ground for the LED to work). Where did you tap for this source?
Does the pin 5 indicator LED illuminate when the latching relay is activated?
