i don't have one, but the ones i always see/read about are put behind the license plate and use wing nuts on the plate for quick removal to hit the switch.
I put mine behind the plate using standoffs. The FR switch is called the "Big Switch" for a reason. The Moroso switch isn't as big on the outside. Do a yahoo search on battery relocation. That's what I did to get some ideas. Check out my site here on the photo page to see pics.
