The one you are looking for most of the time is directly in front of the engine. It goes from alternator to the body via a 6 inch or so wire, that connects to body in front of and near the fuse box. This is the one that usually goes bad, due mainly to vibrations or a bad motor mount(s). Fix the mounts if you change this ground wire or it will break again.
