Need Help!

[spankme234]

I was driving to the gym today and when i got there i turned off the car. I noticed that my seat didn't move back. So I turned the key and there was no power. I poped the hood open. I saw a wire harness hanging, not connected to anything. The wire is from the fuse box. It connects to the two main fuses in the box and comes down. Now the wire runs into a black harness that is pretty close to the battary. ( the reason the wire came loose is my battery is not all the way secure so it slides a little and i guess it slid into the harness disconnecting it or breaking it.) I had people trying to help me find how reconnected it, people that are mechanics and they couldnt find where it connects to even the aaa guy couldnt. Any idea where this harness connects to?(the black harness connects into a red harness they were both connected but the other side of the red harness is what came off) Thanks in advance for any help
