If you look at your PDF for the LED board, I THINK you need 2 meter signals wires, which you have, 2 AC wires which you have and are violet from that terminal strip, and a ground from the star ground.
This is from memory, you'll need to check and verify.
Anyhow that OUT 1 wire comes out, you've replaced it with a wire "further downstream" after the relay at DCP.
