ok, just to add to what's been said, yes, easiest way to do it on an automatic is to use the clutch grommet that has been pointed out already in this thread. simply pry it right out, drill a hole just a little smaller than the cable so that you can fit it through with some WD-40/light coat of oil on the cable. behind the grommet you'll see there is some crappy factory sound deadening material on the firewall... poke a little hole in it too so that the cable can pass through. then just feed it through about 30cm or so, open up your fuse box in the cabin and have a look around and you should be able to see the cable. From there it's just a case of feed/pull, feed/pull and run it where you want.
