You got a diagram? Mine didn't come with one. If yours are the same just position the mats where you want them, screw the thing into the carpet in the middle of the mat hole so it marks the carpet with a pinhole, remove the mat, screw the bottom bit into the carpet so it's tight, clip the other bits into the mats, put mats over the top and turn the little clip thing. Really good system if it is the same thing, I'm sure you can't be struggling with them that much as long as you haven't had too much to drink!
