Single Fan Connector CTOR

The Single Fan Connector CTOR is a dedicated wiring harness pigtail designed for direct integration with electric cooling fan systems, particularly Northern Radiator fan assemblies. This component exists to simplify the electrical connection between your vehicle's fan motor and the engine bay wiring loom, eliminating the need for field-spliced connections that compromise reliability and longevity. Whether you're upgrading to an aftermarket cooling solution, rebuilding a radiator system, or swapping a high-performance fan setup into a custom build, this single-fan pigtail provides a clean, factory-style interface that any competent DIY mechanic or professional shop can install in minutes.

The harness uses a molded connector body to ensure secure seating and corrosion resistance—critical in engine bay environments where moisture, salt, and temperature cycling degrade bare wire connections. The pigtail design carries the fan motor power and ground circuits in a compact, lightweight package measuring just 5.1 by 0.65 by 5.2 inches with a minimal weight footprint of 0.06 lbs. This connector standard matches Northern Radiator's OEM fan specifications, meaning pin configuration, amperage rating, and insulation are engineered to handle sustained cooling loads without voltage drop or thermal stress on the connector contacts themselves.

Engine builders and cooling system integrators benefit most from this component when assembling custom radiator loops or upgrading factory cooling in high-horsepower builds where aftermarket fans push larger volumes of air. Installation is straightforward: mate the connector to your fan motor's receptacle and run the harness back to your existing engine bay loom or relay block, then secure with cable ties. Compatibility extends across Northern Radiator single-fan applications; verify your specific fan model before purchase to ensure connector type alignment. For street rods, restorations, and modern performance platforms alike, this pigtail eliminates unreliable solder joints and delivers the professional electrical integration your cooling system demands.
