Topless Stang

I recently did a complete audio build out where I stripped my interior. After putting the carpet back in everything else I have this problem. I know it has to do with the little switch that was on the parking brake housing, but for the life of me I can't remember what the correct way of reconnecting everything is. Has anyone else ran into this problem? I just took a road trip and CC wouldn't engage because it my car thought the brake was still on...not to mention the fact that the annoying constant beeping is slowly driving me crazy!
