EFI Fan Wiring Kit

The EFI Fan Wiring Kit from Cold Case Radiators is a crucial component for those upgrading to electronic fuel injection cooling systems or retrofitting classic vehicles with modern engine management. This kit connects your engine's ECU to aftermarket electric cooling fans, eliminating the need for mechanical fan clutches that can waste horsepower and reduce efficiency. It is ideal for enthusiasts building restomods or upgrading carbureted engines to EFI.

This wiring harness is designed to ensure reliable fan engagement based on coolant temperature rather than engine speed. It includes all necessary components for integration with electric cooling fans, including conductors, relays, and connectors. These components are engineered to handle the electrical demands of modern fan motors, ensuring efficient operation without voltage drop or heat buildup.

Technicians and car enthusiasts working on fuel-injected engines will find this kit beneficial for various applications, including LS swaps and 5.0 Coyote builds. The compact and organized layout of the harness minimizes installation time and reduces the risk of incorrect connections that could damage the ECU or fan motor. This kit is an essential upgrade for anyone looking to improve their vehicle's cooling efficiency.
