sorry i have kind of vandalised your drawing abit, but I hope it makes a bit more sense, let me know if you cant understand it.

The Black on top, and green on the right, connect to the ATX on one PSU, and the Yellow on the left and black at the bottom connect to the same colours on a MOLEX on the other PSU, i have done it colour coded for you...

Really do hope it helps.

Here ya go anyway.

Start by connecting the 12v rail (yellow wire) and a ground (black wire) from one of your primary power suply's molex connectors to some bare wires that we will connect up to our relay. (see picture 1)
Looking at our relay as if the bottom is where the unconventional pin is located, attach the incoming 12v(yellow) cable from PSU1 to the left pin and the incoming ground (black) from PSU1 to the right pin. See picture 2. We used alligator clips in this instance for testing. Make sure you securely solder the connection if you are doing this permanantly.
Moving over to PSU2, Connect 2 lengths of wire to be run to the relay to pin 14 (the only green pin on PSU2's ATX connnector) and a length of wire to any of the black (ground) wires on the 20-pin ATX connector. See picture 3 for guidance. These pins will act as the relay's pathway to tell the second PSU to turn on.
Run the hot lead ( the green pin 14) to the top of the 12v relay circiut ( see picture 4). Again, make sure you solder it to secure the wire to both the pin and the relay. Run the outgoing ground to the unconventional pin on the relay ( the unconvential pin is reffered to as the pin that is on the right side of the relay in the photo).
Plug PSU1's ATX connector into the board and let her rip. You will hear a definate click noise as the relay is open and then closed to turn PSU2 on. On our test set-up, we attached a green LED in place ( see picture 5), which is power off a molex connector on PSU 2. It's glowing in our photograph, so that tells us everything is working well.
