I did it myself. There's write-ups on how to do it. I think the website where i got my info was rubicrawler.com or something like that. Just look for a write-up on how to do it. You just need a rocker switch, about 10 inches of electrical wire, a drill and patience. It didn't take me long. About half an hour or so. And it's not hard to do at all. The rocker is only like 10 dollars at autozone.
