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.
