WTF? This is really easy stop making it sound hard---There is a huge hole already in the firewall for the factory fog light harness use that hole near the brake pedddle. Honda can even supply you with a gromet to seal off around the wire, how hard is that. Run the biggest wire you want it should be fine. See your dealer for directions if you need. www.Handaaccessories.com even has them online for you to see.

Hope this helps you--if you run the wire per-factory style you'll get less grief if you ever need to have it serviced. You can even run you power supply the same route as the fog light harness and keep it out of the way of things. If you have foglights even better just zip-tie to the already there harness.
