    The fan only needs to run when the natural airflow is insufficient, so when the coolant from the radiator is still to warm.
    When driving, the 55+ MPH wind forces enough airflow through the radiator to cool the engine. So the fan is not needed, and in many cars the ECU will turn off the electric fan.
    When you slow down, stop, are towing, going up steep incline, etc. the natural airflow may not be sufficient, and the electric fan should come on.

    Put the sensor in a hotter spot you just keep your fan running more often. This just puts unnecessary wear on your electric fan and alternator.

    There are two sensors in the truck related to temp. One right where the thermostat is and another between one and three. Can I should I use one of those locations?

    My '93 GMC K2500 454 TBI has a small pusher fan in front of the A/C condenser. Is that what you're talking about or is it in front of the radiator?

    Ether location will work, but you need to add another sensor. Summit racing, and Jegs sale a spacer that fits under the thermosat housing to give you a place to add a new sensor. You should not remove one of the OE sensors and replace it with one for your fans. It would be better to add the sensor for the fan. Most setups I have seen, have the sensor on the upper radiator hose, thermostat housing area. Here are pics of mine. 20180718_195453.jpg 20180718_195530.jpg
