Using this product is easy. First, locate the old connector on your Dodge Ram 2500/3500's Cummins engine. Carefully remove it, then connect the new replacement connectors with 6' pigtails at both ends. Make sure the connections are secure. When installing, avoid pulling too hard on the wires to prevent damage. For maintenance, regularly check the connections to ensure they are still tight and there are no signs of corrosion. If you notice any issues, contact our support team right away. Remember, this product comes with a 6 - month limited parts warranty, so you can use it with confidence.
