New red cable goes to the old poisitive
New black cable goes to chassis ground
Battery goes in box
Box goes in car
Make SURE you buy a fuse for the positive side of your cable and wrap all cables with plastic protection where they pass through holes and what not. If you dont do this and your positive shorts, your floor will literally melt (and i am not joking) infront of your eyes.
