The other day I am driving my Ranger, using my ignition key EOC method and I got to thinking, I really need to get a FI cut off switch.

So, I started thinking about where to mount it.

Side of the shifter?

Nahhh.

Side of column?

Maybe.

Somewhere on the dash?

Maybe? But where. Then it occured to me that I already got a damn switch in the perfect ergonomically located position when my hand is on the shifter in 3rd or 5th gear. Just stick out my thumb and it hits the cigarette lighter!

What if I was to disconnect the hot wire from the back and run the FICO wire in it's place. A cigarette lighter that is depressed in pretty damn close to being a short. It has to be to get 12 volts to make something hot enough to cause a fire in a few seconds. When I get home I will ohm it out. I suspect it will be less than 2 ohms which hopefully will be enough to pull the FI signal low.

And, this is the perfect stealth switch and also a handy theft deterent device.

Has anyone tried this yet?
