I dont know man, to each his own, but I like a clean install free from sight and I can't imagine opening my door and see a huge blue wire staring at me. Just look for a big grommet on the drivers side, you can drill through but its easier just to pry it open and push the wire through. I have all of my gauges ran through and about to put a 4g wire through with no issues.
Where on the driver's side? and if you look in the pics.. I have the plastic piece pulled out.. the piece is now in and covers the wire.. can you take a pic of this gromet?
I did find some locations that people were telling me about.. but it didn't seem as easy as they said.. looked like some drilling was needed etc.
