All 1st gens have a factory engine block heater used in the colder climates, to help your engine start in lower temperatures. Often times 30 years later, these cords have rotted, been removed, or are just plan worn out and showing exposed copper wires.
Easiest way to get your block heater working again for those of you who use your trucks in the colder climates, is to replace it with a new cord.
Will fit 1989-2023 Dodge Cummins trucks.
