Engine shutdown? That's in the ecm, and you would have about 33% chance that you would have a Series 60 in it. The other engines had mechanical pumps in 1989, so there is no shutdown.
Unless you mean something else.ProfessionalNoticer and Big Road Skateboard Thank this. -

But someone disconnected all the sensors and the box
I got all the new parts temp switch and oil pressure switch, coolant sensor ant the medallion shutdown module
The truck has the flasher relay for the warning lights on the dash
Just need to figure out which wire number goes where
Because it’s option it’s not in the wiring diagramBean Jr. Thanks this. -

So it just uses the module to break fuel solenoid signal?
Looks pretty straightforward. Neat stuff, never seen that beforeBean Jr. Thanks this. -

Never seen one of those still connected after the warranty expired. Like @kranky1 stated. On trucks with Cummins They would always glitch and shutdown fuel for stupid reasons. Everyone cut the wires on those after a few years. I have the original one in the dash of my ‘72 White. As far as I can tell it hasn’t been hooked up for 40 years or more. Lol!
