What to splice for poor mans alarm
 

Any one know what this diagram is that I have drawn? I want to install a poor-mans killswitch or alarm, The only problem is does anyone know which pin would be the hot pin on the underhood fusebox? Or in other words, which pin to switch? (actual relay does not have these numbered this way)https://cimg7.ibsrv.net/gimg/www.cad...8163b44e09.jpg
