Im wireing up ******* fan control curcuit with the Derale #16759 fan relay and i was wondering if anyone that reads this has done the same, and how you adjusted it. the little screw to turn for adjustment doesnt have temp markings at all, so do you just get the engine at the turn on temp you want, and play with the screw until it just turns on? i dont have scan tools or equipment yet so i cant see the temp any other way besides the stock guage.

thanks
