easiest way i have found to run a power line from the battery through the firewall is to find an existing hole with grommet in firewall. i found a plug in the firewall of my car that has the antenna going thru it. i took a knife and notched it on 2 sides so that it would push thru. i use a straightened coathanger with a small hook formed on one end to old the wires. after grabbing the power line with that use electric tape and use that set up to pull it thru. i do the same thing when i run speakers in my doors and to get in places where i have more trouble to access.
