Juan L. –
Excellent bit of kit.
Cleans up that relay box you have with a nice clean simple unit. Can be controlled using pos or neg triggers and for multiple outputs.
pay close attention to the wiring requirements though as to not overload a wire and cause a fire risk.
People will always say i can build this for cheaper and that is possible but these are fully solid state relay not the clicky moving type and it’s all done for you with simple plug and play. some things are just easier to buy and put in the car so you can concentrate on the wiring job at hand.

This worked great for my dual fans.
They trigger/ activation with ground temp on at 190degree then off at 180 Degree.
I also tapped into the power supply from the AC control to the binary switch and connected that to the positive trigger/ Activation so the same fans turn on when the AC is on and not dependent on engine temperature.

Expensive but well worth it.
Saves a lot of wire and space. Easy to set up.

Great price for a high quality product. Used in a volleyball efi conversation on a mustang to handle electric fans and fuel pumps.
