-In regards to the fan, direct to the battery is one option.
-But as I was wiring the fan, I thought about the starting solenoid and seeing as I can’t get to the back of the starter (against the head almost), well comments below.
- On the right side of the starting solenoid as you are facing it. Looks like a brown wire.
-I have 12v= Key on only on this side (brown wire) and zero bolts with key off.
-Question, can I run the fans relay off that stud so I’ll have fan off when the key is off?
-Just thinking about it.
Thanks,
-Question: how many of you wire directly to the battery and let the fan controller do its job to cool the water in the radiator down when you park?
-Directions say it can be either direct, or off when the key is off?
-I don’t have a new car (1986 is my newest/Jeep) and I know those run electric fans and they run when the key is off on some vehicles.
Thanks,
JB
My controller runs for about one minute after key is turned off.
Auto Cool is really a nice unit. No relays, pulse width modulated that allows a soft start for the fan, no voltage or amp spike because the fan doesn’t start from a dead stop. Fans are powered by the controller instead of being powered by the battery.
PWM is transistors rapidly turning the fan off and on, as temp increases so does fan speed. There is also a fail safe option on this controller that can be hooked to an in-cab toggle switch that, when switched, maxes out fan speed.
The idea behind putting the sensor on the outflow side of the radiator is to regulate the water temp entering the motor instead of trying to manage water temp leaving the motor.

That's nice, soft start and all.
Do you have a product link?
Never heard of it until now and I bought the Hayden in 2017 but never got to install/working on truck.

I’m using the 85 amp controller. They aren’t inexpensive. Google the reviews and decide for yourself. I really like mine, keeps my temps steady. I installed mine in Oct. 2018, zero problems in SoCal summer heat. https://www.autocoolguy.com/
