Battery Relocation Question

I ran mine inside the car down the drivers side with the factory wiring,there is a metal cover over it from the factory so it is safe either way.also found as per nhra rules you will need a shutoff switch and approved battery box or firewall for speaker shelf and back of seat,and at least 2 3/8" bolts thru the steel battery holder and the frame of the car if you plan on going to the dragstrip.hope this was helpful.
