Kill Switch

[splats]

For an even easier way, take the smaller battery cable to the main fuse panel (the one next to the battery) & put your kill switch into it (i.e. battery to kill switch to main fuse panel). You only need to run a two-post switch. The alt. is regulated by the computer, so no need to wiring anything to the alt. (i.e. the four-post switch). I've run this set-up for going on three years & have had zero problems. The wiring on our Neons stink, so I cut/splice as little as possible.

I did mine like Mark describes, super easy and realiable. Spent 3/4 of my time mounting my kill switch in a easy location for driver/safety workers.

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.
