Ok, I really don't know what your problem is (punctuation and correct grammar may help abit) but you can go buy another fuse holder, cut off your old one and hook it up to the wire that you just cut. Then you can get some 12 or 14 gauge wire and run it back to your battery if you want. I don't see the point in running it all the way to your battery though... grounding it on the chassis is basically the same thing. Also, why do you have a fuse on the ground wire? You sure its not the positive power wire?
