have a fox body notch, installing the battery in rear trunk. i googled the rules and regulations for the correct way. aware of the switch on positive side. the only thing i couldnt find was wheather the red/ positive cable must run inside or outside of vehicle? ive seen and heard it done both ways. and does the battery have to be in a inclosed tray metal or plastic? because ive seen cars with just a hold down type or braket not in a box. my local track bitches about things here n there when they feel like it so i would like to do it right the first time. pics would also be nice. thanks guys!
