Wiring in a kill switch.
 

Hello Everyone,
After having my 99 E-250 w/ 4.2 liter motor stolen and recovered by myself 2 months later. I was wondering if anyone has tried this before. I,m thinking of running a kill switch either prior to or after the inertia switch. Which I would tap the Dark green / yellow wire coming from the fuel pump relay prior to the inertia switch. or the pink / black after the switch before going to fuel pump. Just a 12V on and off toggle in line. Any ideas or suggestions would be appreciated.
Thanks , Willieb

Go for it , just don't advertise your plans !!!

Thanks Hanky, I hear ya there about advertising. Will sleep a lot better once I have something else.

Back in the day,, cig lighter interrupt or even head phone jack plug type disconnects were a simple anti theft. Not too many would suspect a missing/eject cig lighter, or an empty phone jack socket, nor do too many crooks carry extras. A hidden switch either in most cases if an attempt at night. Which ever, be sure it doesn't cancel fuel at an inopertune time...
Probably would never happen again, but being prepared never hurts either.
