cut it off and absolutely refuses to restart,until.... (long)

Last night, while I was playin around trying to get codes, I was under the dash below the steering wheel and I saw two plugs that were not connected to anything. One was a regular Ford connector, much like the one that goes to the evaporative emissions cannister, and the other one was a white harness. It was rectangular shaped and was an eight-pin straight female connector. Any idea what the heck that is? I didn't see anywhere to connect either of these under there.
