Cooling Fan Harness w/ Relay

The SPAL Advanced Technologies Cooling Fan Harness with Relay (model 195FH) is an essential component for vehicle builders and mechanics integrating aftermarket cooling systems into custom engine builds, performance upgrades, or restorations where OEM harnesses do not meet modern fan specifications. This harness simplifies the process of routing power directly from the battery to high-draw cooling fans, providing a reliable solution that minimizes voltage drop and protects your electrical system.

Designed with an integrated relay, this harness isolates the cooling fan's high current draw from your vehicle's stock wiring, reducing strain on factory circuits and thermostat switches. It features heavy-duty connectors rated for sustained amperage and proper gauge wire sizing, ensuring efficient voltage delivery under load—critical for electric fans that can draw significant current.

Ideal for those upgrading to larger capacity radiators or building custom vehicles, this harness supports both manual switch and temperature sensor control options. Its compact dimensions allow for flexible routing in various engine bays, making it a versatile choice for any automotive project.
