Finished building and running my 1/0 gauge starter and battery wires, trunk mounted the battery, mounted the relays still gotta finish wiring those up. I'll clean everything up and make it look nice later once the rest of this wiring is completed. Also going to put in a battery kill switch in here as well. Battery box is bolted to a plate which is bolted through the trunk floor and through the rear frame, I'll probably end up trimming the plate for looks, and leaving a tab on there to mount the kill switch. Starter wire (only hot when starting) runs through the frame on the pass side and bolted in spots with cushioned clamps.
