Dodge HEMI
Hey guys I was just out looking at my truck, a 2003 Dodge quad cab 1500 with a 5.7 Hemi so I could order the wire to run the big 3. Now here is what i was wondering about, their is a small wire (stock) ran from the Alt to a fuse box in front of the battery, it connects to a bolt there and then another wire runs from their to the battery.

Now my question is.....does this wire connect to something else at this fuse block or is it just the charging wire? What should I do here? Skip this and just run to the battery and alt? I have no idea. If someone can help that would be awsome, if pictures are needed i can try to get some taken. Thank you.
