Well I believe my negative battery cable is bad. I am looking to replace it but the dealership wants $350 for all the cables. Is there any way that I buy a cable and just replace the negative cable? What all does the negative cable go to? Also about how long is it?
You could go a couple of different routes to replace it. If you want it to be factory, it's part of the harness with the O2 sensor wiring, and the cable is pretty expensive from 50 Resto. The cheap route is to make your own from some welding cable. The process I like to use is listed here from a previous post I made:

The best way to go IMO is to pick up some welding cable and ring terminals like these to make your own cables:
Heat the terminal with a torch, fill it with solder, and shove the wire in while the solder is still hot. Put some heat-shrink tubing over the connection, and you end up with something better than new, without having to crimp on a connector and risk a bad connection that has a lot of resistance.
You can do that and either open up the harness and remove the factory wiring like I did, or just cut it off and abandon it in place. To open up the stock wiring harness, it's really not a hard job at all, and should probably only add 20 minutes to the job. All the stock harness consists of is the battery cable, and the wires for the O2 sensors, that are wrapped in electrical tape, making them essentially another harness, and they're enclosed in wire loom that's taped in a couple areas, and has some brackets kinda crimped over it in another, so it has attachment points under the car and doesn't hang free.
