(That "M" might be "AA")

This is a can with 4 tabs, a relay actually, with a coil, and a single set of contacts.

The truck runs just fine without it, just curious what it was supposed to do?

(Thank you)

BTW: If there is anyone within 50 miles of NYC who knows their way around IDI, please let me know!

The can is a SPST (NC) relay
The capacitor is across the coil to prevent "chattering". The coil is OPEN, but I have no idea what excites it, or what the NC contacts interrupt when the relay energised.

Other than the black plastic connector skirt, it looks exactly like a pre-airbag horn relay. What are the WIRE COLORS in its connector? That's how you ID electrical parts.

I will try to specify wire colors when it's light. This cannot be a horn relay because the contacts are normally CLOSED. Energizing the coil interrupts a circuit. The coil is blown out (open) so the contacts would ALWAYS be closed. The relay is unplugged for that reason!🙂

I don't know my way around diesel engines at all, but I understand electronics a bit....
