I did the app. to the the gov. for my 98 XJ. It was no big deal. My son likes to ride up there when we Jeep. He is still small so having the switch works out. The neat thing for Jeeps are that Jeep has a plug in kit for it. Worked out quite well. Once I got my OK back from the gov. I got a few solicitations in the mail for kits, nice how the gov. works that way. If you have a real need for the switch, go for it, but if you don't, don't bother with it, it will cost a few hundred to get it done.
