The previous had a small little 16 guage power wire running somewhere (dunno what he was using that small of a power cable for) off the battery, I was gonna follow it down but when I unhooked it i noticed itd been cut, so i found the rest inside the car (it was under left drivers foot rest area) and yanked it. Anyways I'm assuming there is a firewall on the drivers side that I can run it through? If so, how do I get access to that cause by just looking i dont see anyway in, or is there another way that might easier? Thanks in advance
