Review on FAERSI Electric Cooling Fan Thermostat Kit - 175-185 Degree Temperature Sensor Switch with 40 50 60 AMP Relay Kit by Gopal Baltimore

The instructions could be a lot more detailed but this is a very basic relay so better instructions and diagrams are easy to find elsewhere. Note: This will only work if all wires are properly connected. The brown wire needs to be connected to a 12V power source. Also, only one sensor adapter is included, so prepare to find everything you need for your purpose. I'm a little concerned that the relay case isn't airtight, so I installed it with a more protective cover and waterproof connectors welded in. instead of the most important. Let's see how it holds up.
