Ignition Switch Wire & Emergency Brake

I'm trying to find the hot wire that comes off the fuse box and goes to the ignition switch. As far as I can tell that wire is gone and I need to run another one. Can anyone tell me where It connects into the fuse box? I someone has a diagram that would help.

I'm also looking for a good diagram to reconnect the emergency brake cables. I'm hoping I have all the parts to do this and don't have to go back to the Mustang supplier, again today.

Don't ask me what the PO did to the wire. Many things he did were a mystery as to how far and how much he tore this car apart.

After scouring the internet I found what I was looking for. Now my question is: what goes on the end of the brake cable that comes from the firewall that holds the cable to the "bar"? That's a I'm missing. If someone has a close up shot of this I would appreciate it.
