i have an 03, there is a hole to the left of the brake pedal, where the clutch is ran through the firewall, (considering you dont have a clutch) drill through, perfect for 0 gauge //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
I have an 07 Fusion, there was a white piece of plastic above the gas/brake pedal. A round something, that was more than big enough for 0 guage. I drilled threw it from under the hood,(goes through the firewall) then I had to run all the wires under the floor carpet. Hope this helps
