Ame, I linked a drawing in the post. Please check hyperlink - "image"Your cable order in the drawing is 3.3V, GND, GPIO. The pin order on the relay module is 3.3V, GPIO, GND. Can you post a photo of your wiring?
Have you tried a really simple program to toggle the relay? If you can get basic functionality working then the other stuff should work.
Also yes, I have tried really simple LED turn on and off. Oddly it works fine. I should've included it, when It is connected PSU, it works abnormally.
