Was at the Goodguys car show today & came across an adjustable thermostat for the spal fan I have. Right now I have it hooked up with a manual switch & relay setup. The fan control unit I bought has only 3 connections 1 for the fan motor,1 for 12volts & the other I don't know what it means. It says the last wire goes to the compressor coil. Can anyone help me out with that. I assumed there would be some sort of ground & thats what this wire is for, but I'm not sure.

I'm not sure if you're into buying something else....
I have a Hayden model that controls both of my electric fans. It's got a built in thermostat with a temp probe that you push into the radiator. When it hits anywhere from 160-195 (depending on where you set it), the fans will both come on. It also uses the A/C Clutch turn on. Like I said it powers both fans with the same thermostat, so it was the clear option for me.

Thanks for the tip on the compressor coil.jmlay71 said:
This unit is actually supposed to turn on/off at whatever I set it at. How I have it now is a Bosch relay & a toggle switch. I'm going to leave the switch & relay in & try to wire the fan control unit to the relay. Im going to set it to turn the fan on around 195 & off at 180. Only thing I can't figure out is if I need another relay. Right now I have the toggle hooked up to 87 of the relay, thats where I'm supposed to wire the fan control unit to. I see on the relay there is a 87A, Im not sure if it's possible to wire it up to there?
