674-00923 Dual Electric Fan Harness Overview
674-00923-style dual electric fan relay harness for common GMT800 electric-fan retrofit and service applications.
This 674-00923-style dual electric fan harness is commonly listed for GMT800 truck and SUV applications including Silverado, Sierra, Tahoe, Suburban, Yukon, and Avalanche platforms. The assembly uses a twin-fan branch layout, relay bracket, and power leads to control two electric cooling fans in retrofit or repair programs. ENJOE can support matched harness production, aftermarket packaging, and project-based connector verification. Because fan connector, trigger strategy, and engine-platform details can vary, the original setup should be reviewed before order.
