Battery Shutoff switch location question
The "switch" itself can theoretically be installed anywhere but no matter where it's located, it has to be easily actuated outside the car by track personnel in case of emergency. Often the switch is in the trunk which generally can't be seen but as long as there is a way to find and actuate the lever quickly then it's fine.
If you do put it underneath where you show in the pic, you'd need to have a lever attached to it in clear view for access and marked indicating what the lever does (i.e; "push off"). I looked at doing it that way myself but decided against it because I drive my car on the street. With the switch underneath, you'll have to run the wiring through the floor and as everyone understands, street driving will always increase the chances of "something happening". Previously I had the cutoff switch under the rear bumper which is similar, just not as far forward. While easily installed and accessed, running all the wires through the floor was less than ideal.
Here's what I ended up doing. Don't mind the mile-long handle, this pic was just for mock up, it will be trimmed to where it's just and inch or two off the bumper. It can also be easily removed when not at the track. To actuate the switch only takes about an inch and a half of movement. Having the switch bracket a little more forward helps to keep the cables slightly shorter. if I switch to a fuel cell, the lever would have to be reworked to put the jog farther back but the concept would the same.
The reason I went though all this was because I didn't want to drill any holes in my tail light lenses or pristine rear panel. There's a small area in the upper right corner of the license plate opening where the lever goes through but to reach the switch obviously required the lever to be configured the way it is. Eventually there will be a "push off" sticker on the bumper.
I know my method is not typical. If you don't care about drilling a hole in the rear panel or tail light lens then that's probably the easiset way to do it.
