The kit included everything I needed — wiring, relay, fuse, and a switch — all clearly labeled and ready to go.Installation was straightforward, even for someone with basic electrical experience. The wiring is thick and well-insulated, which gives me confidence it’ll last through heat and vibrations under the hood. The relay and fuse are a nice touch for safety and protecting the electrical system.Since installing, the fan kicks on exactly when it should, keeping my engine temps stable during hot weather and heavy traffic. The switch is solid and easy to operate from inside the cab.Overall, great value and a reliable upgrade if you’re replacing a mechanical fan or adding an electric fan setup. ### ⭐⭐⭐⭐⭐ Automotive fan wiring kit. *by G***Y on March 30, 2025* Wiring of 2 aftermarket automobile fans.Worked fine and is a very well made wiring harness.
