2003 positive battery to fuse box cable

Any help would be appreciated. I have to replace the approximately 6 gauge wire that runs from the positive battery post to the fuse box. It was all corroded where it attached to the terminal. Inside the fuse box the wire splits into 2 wires. The larger wire connects to the alternator fuse and the smaller wire to the abs2 fuse. Any idea what part this is or where to get it? I can't locate it anywhere. Thank you! I've learned so much from everyone here!
