kill switch

Can anyone tell me how to install a basic kill switch?

FIRST YOU HAVE TO TEST FOR THE STARTER WIRE.   THE STARTER WIRE IS THE WIRE THAT HAS A 12V SIGNAL ACROSS IT ONLY WHEN CRANKING TO THE FULL POSITION THEN ONCE THE KEY IS RELEASED BACK TO 0 VOLTS.  AFTERWARDS YOU CUT THAT WIRE THEN USE A COMMON BOSCH RELAY IF YOU HAVE A ALARM IF NOT THEN USE A SWITCH.  WIRE THE SWITCH SO THAT IT IS NORMALY OFF AND THE CAR WILL NOT START.  SWITCH IT TO THE ON POSITION AND THE CAR SHOULD START.  IF YOU HAVE AN ALARM WIRE THE CAR  SIDE TO 30 AND THE STARTER SIDE TO 87a.  YOU WIRE 12V+ TO 86 AND NEG OUTPUT TO 85.  LEAVE 87 OPEN PLEASE COVER WITH SPADE.   FROM THERE WHEN DISARMED THE CAR WILL START WHEN ARMED THE ALARM WILL SEND A SIGNAL TO THE RELAY USUALLY 12V+  (READ INSTRUCTIONS CAUSE ALARMS MAY VARY) AND WHEN ALARM IS ARMED WILL OPEN THE RELAY AND THE CAR WILL NOT START UNTILL DISARMED. ANY QUESTIONS OR ERRORS EMAIL ME AT REDCIVIC00@HOTMAIL.COM AND I WILL BE SURE TO ASSIST TO THE BEST OF MY KNOWLDGE AND I AM MECP CERTIFIED.  PEACE  certified for the job
