pin outs of relays

[Rob F]

You have the original boards before the next 8 relays was thought about, you don't have the header on the connector board for the other relays which the new boards have.

Anyone with the original boards that has the ethernet circuit (unused) needs to solder the wires directly to the power bar board that the mega 2560 plugs into.

Here's a diagram showing the original board, this is the bottom of the board where you should solder the wires to.
