Want to put in kill switch ?

[SHAWN056.0]

I was wanting to put a kill switch in my 05 F250 and was wondering if anyone could tell me where the starter wire was located and what color it was. I was thinking of putting a relay on it and a hidden switch somewhere. Thanks for any info.

here is a better option find the 12v supply wire to the ignition and place a cutoff switch in it. this will kill all the systems when you try to turn the key and its off only thing would be don't hit it while driving or the truck will die.

right side of engine right next to vaccume pump, connector is round/black one wire. you squeeze the sides to make it come apart
