I just had a quick ? on my radiator upgrade I have the z1 ultimate cooling package and am unsure of one wire. It says it goes to solenoid what i am assuming would be the thermatic switch but it doesnt come with kit and Z1 says not required. Any help in where to route this wire to turn fan on/off without a toggle switch or without having it run constantly would be greatly appreciated. There are the 2 sensors on the upper water pipe one for the engine temperature sensor and other is thermal transmitter and I was thinkin it would wire into the second the thermal transmitter. Like I said any help would be greatly appreciated.
