[updated:LAST EDITED ON 13-Apr-02 AT 08:38 PM (EST)]heck is this? there is a little toggle switch located behind the fuse cover panel to the right of the fuse box itself. Its not an ignition cutout cause the truck still started. I can't figure out what it does!
I know jack about wiring, but its connected to some cabling to the left of the fuse box. ('00 250sd) It's gotta be something added on? Maybe the wife put in some kind of transponder to track me?

 

Many alarms don't just disable the vehicle by switching it when off . You usually have to go through a certain number of steps . Alternately , the brain of the alarm could be bad and thus it just doesn't work
