Battery Shutoff switch location question

I appreciate all the input - maybe I can clarify. I've attached another pic that I've marked up using my awesome editing skills.

I've drawn the switch (it's that black rectangle thing) approximately where it will sit below the floor. The dashed silver line is where the rod will be. Note that it will be directly in line with the bottom section of the bumperette. With the bumperette in place, the rod would not have a handle, and the end of the rod would fit inside the bottom of the bumperette. In that configuration, I could reach under and operate the switch if I wanted to.

At the track, I would simply remove the bumperette, put the handle on the rod, and put the "PUSH OFF" sticker on the bumper above the handle. I would make sure it is CLEARLY visible to track staff.

I plan to put some sort of shield over the switch to protect from water and debris. The only real downside I see is having to run wires through the floor, but it does avoid me having to put a hole in the sheet-metal above the bumper, or through a taillight.
