Fan Pigtail Weatherproof C6

The Fan Pigtail Weatherproof C6 by DeWitts Radiator is a purpose-built wiring harness designed specifically for Chevrolet Corvette cooling fan circuits on 2005–2013 models. This connector assembly solves a critical problem for enthusiasts upgrading electric fans, installing aftermarket cooling systems, or replacing factory harnesses compromised by heat damage and corrosion. As a mechanic working on high-performance builds, you'll recognize this as an essential bridge between modern fan controllers and factory or upgraded radiator fan motors.

The weatherproof design protects against moisture intrusion, road salt, and thermal cycling—critical factors in engine bay environments where traditional connectors fail prematurely. DeWitts' reputation in high-quality radiator and cooling solutions extends to this harness, which features sealed connections that prevent corrosion at contact points. The pigtail configuration allows straightforward integration into custom cooling setups, dual-fan configurations, or direct fan replacement without rewiring the entire circuit. At 0.06 lbs and measuring 3 × 0.95 × 5.65 inches, it's compact enough to route cleanly through tight C6 engine bays while maintaining full accessibility for future service.

Corvette owners pursuing improved cooling capacity—whether through LS engine swaps, turbocharging, or track use—benefit most from this harness when pairing it with modern PWM fan controllers or high-flow radiator assemblies. Installation is straightforward for anyone with basic automotive electrical knowledge: disconnect the factory connector, splice or plug in the weatherproof pigtail, and secure harness routing away from moving components and heat sources. Compatibility is confirmed for 2005–2013 C6 Corvettes; verify your specific fan motor connector type before ordering to ensure seamless fitment with your cooling upgrade strategy.
