Unique Ideas for Gas Cap Location??

I was going to use my old gas cap location for the electrical shut off for the Demon. I talked to the NHRA & IHRA tech inspectors, I was told that the shut off had to be on the rear of the car. Mine still has the OFF/ON switch hooked to it, but I put another one on the tail light panel to make them happy. It's a neat installation & conversation piece, it is just for looks though. FYI, I saw one that had a volt meter installed in the hole.
