I talked to a guy at the track that had one since I am thinking of buying one. He said that the cover where the active handling light is pops of easily and you can wire it into that.
I asked him about the fit, and he said that the flameballs are custom made so the fit was no problem. He loved it and highly recommended it.
I sat in the car and tried it out. After two days of track use, it was a little slick, so it got me to thinking about a different one that is leather instead. However, if I don't go with a leather one, it will be the flameball all the way.
