Okay hear me out... I obviously know that the push/pull and manual "turn style" disconnects are legal. But lets take some things into consideration. I don't want a giant switch on the back of the car, nor do I want a rod protruding into my trunk as I've managed to keep my trunk functional and stock appearing. I also don't want my primary battery wires outside of the chassis (similar to people that put a manual switch on their rear bumper). I drive my car often on the street and don't really want a switch exposed to the elements.

My solution; use a battery isolator relay in conjuction with a small(labeled) water proof switch on the outside rear of the car. Wire up the battery isolator relay so that it meets the legal requirements of disconnecting and killing the car.

Do you think the 3-4 times I may take this to the track a year that the tech officials pass this? I dug into the NHRA rule book and found nothing referencing anything other than labeled, kills car and if using a rod/cable has to be 1/8 dia. Also said switch cannot be plastic, thats easy enough.



Coming here to ask this because noone on facebook seems to grasp my needs lol.
Switch behind the license plate and remove the plate at the track. They have a rule about must run with plates on, hope not.
