Which Sensor?

[Grant Lenahan]

regardless of what fan is blowing, if the motor goes only to 60 deg C, the thermostat is not working.  With a shut thermostat you could have solid ice int he radiator and it would not make one bit of difference....

The radiator fan comes on shortly after the car is started and continues long after the car is stopped.  Engine doesn't get a chance to warm up, only goes up to 60C or so.  The temp sensor on the radiator itself would be responsible for this, right?  Can I simply disconnect the sensor and the fan will stop running?

Background:  when we got the car, the wires inside the rubber boot covering the sensor were completely rotted out.  I threw out the rubber boot, installed spade connectors on the wires and connected them directly to the sensor - three wires out of four, that is.  I looked at the position of wires in the boot and connected them accordingly;  however, there is still some lingering doubt in my mind whether I did this correctly.  Would anyone be able to tell me the colours of the wires that go to each sensor terminal?
