Thank you SpeeStep.
I guess I didn't make my question clear. I don't need to know what to connect the plugs to. They, as it turns out are six pin connectors and are labeled P7 and P8. Since I have never seen that sort of connector before, I wonder what they are for? The quick answer would be to connect to a device that requires them but that falls short of the question. What sort of device would need them?
Thanks again.
