Wiring help for trunk mount battery

Concerning the alternator output wire, I'm running a one wire alternator in my drag car. There is no factory wiring at all, meaning there is no alternator 'field wire' as shown in the diagrams. What I had done previously was to run the alternator output, via a number 6 wire, directly to the battery side of the kill switch. The problem with this setup is that even with the kill switch pulled, this wire is still hot. My question is given that I have no factory wiring, where on this diagram would my alternator output wire connector in order for the kill switch to function properly, and by properly meaning that ALL power is cut off when the kill switch is pulled.
The thing is that unless you actually disconnect the battery(s) at the terminal no matter how you wire it there is always going to be some wire somewhere that is hot. The idea behind the rule in NHRA is that all power to the ignition and fuel pumps be cut off via one central switch on the back of the car. Wiring it the way you did (and as I did) cuts all power the everything except the one wire from the alternator to the battery.
