Just dug up a drawing of fan wiring and thought I would post for anybody that needs it while still in my hand so to speak. This will allow fans to be turned on whenever key is on via a toggle or will turn on auto if engine is on and temp is reached. Key always turns fans off so dead battery is not a problem. Do be careful when working on Toy as it will turn its self on auto now. I like the sw to thermal sw to turn on/off at 170 degrees. Jeff C
