Custom Battery Cables Relay to Grid Heater Wires 98.5-07 Dodge 5.9L Cummins

In order to energize the grid heater in your Cummins to aid in cold weather startups, there is a considerable amount of energy supplied through the grid heater wires as each heater consumes approximately 90 amps. Over time, the wires and connections can become corroded, both causing massive voltage drops as well as your grid heater becoming ineffective.
