Kill Switch

[Streetwise guy]

I you just cut into the small battery cable, you leave the alternator and starter main power cables connected to the battery. No issue for voltage spike, and it will shut the car off, but isn't the main reason for having a kill switch to isolate the battery from all the stuff you've just smeared against the back bumper of that Civic?

I also forgot the part about moving the main sterter cable up to the main stud on the fuse box, then running a new cable from B+ to the kill switch big post, and returning from the other big post with a new cable to the main fusebox stud. The only thing left live is the battery cable to the kill switch.
