if there's no firewall on the battery side. just run a wire from the positive side of the battery across the engine to the firewall on the driver side. and just tie strap the power wire to other wires under the hood just make sure it isnt touch any hot engine parts you could be fine. its just like when you upgrade your power wire fromt he alternator to the battery. tie strap it to non hot parts usually to other wires and you should be fine. just gonna cost you an extra 5 feet or so.
