I am in the process of upgrading some wires under the hood and wanted to possibly run some new power wire from the alternator to my battery. Can someone tell me where it is located under the hood. LOL also what does it look like...

 

It will look something like this.

Its on the passenger side of the engine, and looks just like the one TheIcon posted above. If it were a snake it might bite you.
