Describe your issue:

BTT relay shutting down after 20 seconds i have searched the forums and matched the pinouts to match my board with no success have also remade the 2 pin connector to rule out a bad connection. I read on the other discussion to set the gpio pin high, is the setup on the picture below correct or do i need to add something. thanks in advance

I followed it exactly. I have read people have not been able to get it to work because it will shut off before the system boots. Thanks for the reply.

Maybe I’m a bit slow today: Does it mean it is working correctly for you?

No, the relay would shut down before the system booted.

I have no first-hand experience with this relay, but it seems that the firmware on the relay has some room for improvement.

See Firmware source code · Issue #4 · bigtreetech/BIGTREETECH-Relay-V1.2 · GitHub for a discussion and alternative firmwares.
