oil cooler fan wiring

[tablerock]

I've reviewed 101 projects and it says to wire the two temp sensor wires to the two fan motor wires.I lack the wire connector for the temp sensor.The cooler housing has a ground connection near the temp sensor.Am I wiring + to the sensor and - to that ground connection or does the temp sensor have a ground or negative terminal contact on the proper wire harness connector?I want to wire in a manual dash on/off switch also.Thanks for your time.Jim.
