  • Wrong wiring diagram
Many of you like me found that this relay didn’t work. That’s because the wiring diagram is wrong. The black wire is supposed to go to the thermostat switch and the white wire goes to the ignition.

  • Temp control and relay
The kit came quick and looks nice. I am not certain the switch works as I attempted to bench test with a propane torch. however I may not have gotten the sensor hot enough or it did not like the ground. The only reason it gets 4 stars is there is no plug for the sensor in the kit. I get you can use a spade connector which there was not one in the kit however if there was a actually automotive grade plug it would bring this to the next level. Overall good product I like it and it should be perfect ... show more

  • A simple easy to install fan controller. Package contains everything needed.
Only niggle is that the set point is non adjustable.

  • Great product and an even better value
This is a great value for the buck. The thermostatic sensor is worth the price of the kit, Easy to install. Directions could be better. But still very impressed

  • Doesn’t work
Wired exactly via diagram and fan does not work. Bad thermostat? Bad relay? Bad overall product?
