I finally installed a cutout switch in my 63 since my battery is in the trunk and it seems they always let me slide but I wanted to make it right. So to make a long story short my battery is on the left (drivers side in my trunk. Its all stock in the trunk as I use a stock gas tank and when I put it in the cable my buddy had given me was not long enough to reach over to the right rear. So I installed it in a marine case in the left rear as it really makes no difference to me which side it was on even though everyone says the right side is best. So I did not want to drill a hole on my car body so I drilled a hole in the upper corner of the left tailite so if I ever want to change it back to all stock (which I dont think I ever will) all I would have to do it put a new taillite lens in it. I bolted the switch to the battery box and adjusted it so it works great. It sticks out about 3 inches when on and when pushed off its even with the taillite bezel so its not easy to see when its off which I like because if I want to turn it off when I park somewhere I push it off and most wont even see it.
My question is someone told me today that the switch has to be on the right rear of the car ? I never looked at the rulebook to see as I did not think it made a difference. So I am wondering if anyone knows if that is a real NHRA rule ? Thanks , Ron

Don't know about the right side but it needs to be labeled. As far as what is off.

Every one I've ever seen is on the passenger side rear.
I found this on turbo-mopar.com
Mandatory when battery is relocated or on any vehicle running
9.99 or quicker. An electrical power cutoff switch (one only) must
be installed on the rearmost part of each vehicle and be easily
accessible from outside the car body. This cutoff switch must be
connected to the positive side of the electrical system and must
stop all electrical functions, including magneto ignition. The off
position must be clearly indicated with the word “OFF.” If switch is
“push/pull” type, “push” must be the action for shutting off the
electrical system, “pull” to turn it on. Any rods or cables used to
activate the switch must be minimum 1/8-inch diameter. Plastic or
keyed switches prohibited.
NHRA requires you to be a paying member to see it on their website.
I can't find anything specifying either side of the car.

There is no NHRA rule requiring the switch on either side, just on the rear most panel of the car. Quote:
General regulation
8:1 BATTERIES
All batteries must be securely mounted; must be of sufficient capacity to start vehicle at any time. Batteries may not be relocated into the driver or passenger compartments. Rear firewall of .024-inch steel or .032-inch aluminum (including package tray) required when battery is relocated in trunk. In lieu of rear firewall, battery may be located in a sealed .024-inch steel, .032-inch aluminum, or NHRA-accepted poly box. If sealed box is used in lieu of rear firewall, box may not be used to secure battery and must be vented outside of body. Relocated battery(s) must be fastened to frame or frame structure with a minimum of two 3/8-inch-diameter bolts. OEM located batteries without complete OEM hold-down hardware must be secured to OEM battery box/tray using the same 3/8-inch diameter bolt hold-down method described in previous sentence. (“J” hooks prohibited or must have open end welded shut.) Metal battery hold-down straps mandatory. Strapping tape prohibited. A maximum of two automobile batteries, or 150 pounds combined maximum weight (unless otherwise specified in Class Requirements), is permitted. Maximums may vary according to Class Requirements.
8:4 MASTER CUTOFF
Mandatory when battery is relocated, or as outlined in Class Requirements. An electrical power cutoff switch (one only) must be installed on the rearmost part of each vehicle and be easily accessible from outside the car body. This cutoff switch must be connected to the positive side of the electrical system and must stop all electrical functions including magneto ignition. The off position must be clearly indicated with the word “OFF.” If switch is “push/pull” type, “push” must be the action for shutting off the electrical system, “pull” to turn it on. Any rods or cables used to activate the switch must be minimum 1/8-inch diameter. Plastic or keyed switches prohibited. Switches and/or controls must be located behind rear wheels on rear-engine dragsters.
Most of the time the battery is located on the passenger side to help add a little pre-load on the Right rear tire. this can also be done with ladder bars, 4-link, cal-tracs, or good shocks.)

As everyone has said, no matter what side the switch is on. But, you mention a "marine box", is it sealed with a vent tube?

Bottom Line......
There isn't any money in it for NHRA on what side it is on so they don't care.
