Piface and pi connection

[meddyliol]

I have a Raspberry Pi and a Piface, I also have a Raspberry Pi GPIO Port Saver & Adapter to connect the pi via a ribbon cable instead of having it sitting on top . My question, which might be stupid but I do not want to blow anything up is this: If I connect a ribbon cable to the pi with the red line to pin 1, which way around do I connect the cable to the piface?

Thanks

I'd use a DMM as a continuity tester....
