if you take off the wiper cowl (torx screws on the under hood part, regular phillips on the exterior surface, covered with small round plastic clips)
You'll have to take off both sides of the cowl (it's two pieces). Look in the hole by the drivers side and you'll see a round black rubber cap. It's against the firewall, and it unscrews. Poke a hole in the center of it, and run the wire through it. Then put it all back together again.
The wire coming through the firewall will be high up by the brake pedal, have a buddy look for it as you pass it through.
Good luck!
