Yea these things suck. On some cars it's real easy to get to and on others it's a complete PITA. Since you can see the wire from inside the kick panel area I'd assume that's the way you'll have to get to it. Unfortunately I can't picture how any of it is situated so I can't really recommend an easy way to get to it. It may be that the lower dash panel needs to come off so you can get to it, otherwise maybe you can use something like a coat hanger through the hole to fish it out.
