temp

i got a godspeed radiator and it came with electric fans i was wondering if anyone can help me wire them?

at idle my coolant temp is normal but when i start to drive it fluctuates between normal and 3/4 of the way (towards the hot side) what could it be?

the coolant temp gauge on my dash stopped working.... i noticed the wire broke inside the connector, and the coolant temp sensor sender no longer was good so, i replaced the sensor with a new one from toyota and replaced the connector with a spade connector and soldered it together, but still...
