More gauges than gears in a f&f movie, holy cow!
I like the idea of moving the switch to between the seats, then you can easily reach it when you're strapped in and your Nos gauges will be grouped.
But what about those clear coloured plastic switches (blue, red, green) off to the right? If they are part of start-up you could group all the boot-up switches to between the seats, or better yet
on the ceiling like a plane?
