Detailed Product Description

The RU-480 blower motor resistor by Standard Ignition is engineered to provide consistent blower motor speed regulation for Dodge B150, B250, B350, B1500, B2500, B3500, Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van models. This resistor is mounted using screws and features five male blade terminals, allowing it to handle multiple blower speed settings between three and five. It does not include a wiring harness or mounting brackets, so installation requires using existing vehicle hardware and connectors. The absence of a connector means direct blade terminal connections are necessary during replacement.
