T-Relay Chain problems

[carbuthn]

1. I could not find a schematic for the T-Relay Chain board.
2. All of the pictures show the cable that connect the T-Relay S3 motherboard to the T-Relay Chain connected to the left side of the T-Relay Chain board, this is labeled as an output on the board. I was able to get the board to work once I moved the cable to the input (right) side of the board.
3. Would like to know the pin to turn off the red LED on the T-Relay Chain board.

The red LED cannot be turned off, it is the power indicator

I was afraid of that, I didn't have one on the main board, only the chain board. Time for some black paint.
The pictures with the cable in the wrong socket caused me the most problems.
Thanks for the schematic.
