I have one of those shut-down timers on my old FLD with an N14 2000 vintage. It may have been factory installed. I used it all the time. I added the same timers to my other trucks and one NH combine. That way i didn’t have to sit in the cab while it cooled down, especially in the field during harvest. Just wheel into the field, crank the timer on and bail out and run to the next one. The last one i added one to was a 2007 W/Star. I got them from the F/L dealer. Used to be about $100cad but the price has gone up.
