> Use a relay. Just a simple 4 pin 30amp will be plenty. Connect 85 to ground, 86 to the toggle, 87 to the battery through a switch, and 30 to the fan power wire. Then just ground the fan. this will allow you to run a small wire through the firewall which will make life much easier.

Please dumb this down for me a bit. What is 85, 86, etc mean? Also - my battery is under my rear passenger seat (a good 10ft from the fan :))
