Probably didn't come factory-run, if you know what I mean. I had to buy one from Techni-Car (local stereo shop here in Atlanta) for about forty bucks, though since I got bashed pretty good from behind a few weeks ago I'll sell you mine when I get back to the US. I'm overseas currently. Factory-run, its down the passenger side, but you can do the driver's as well. Just be wary of the airbag module and wiring if you go down the passenger side.
I won't be back until April 20th though so if this is time-critical I can't help out much with P/A
