Anyone know what is the difference between the coolant temp sender and the temp switch which is located on the lower intake manifold? I know the sender is what the gauge uses so what does the other do??? The other one I refer to is near the air charge temp sender. Thanks.

You have a coolant temp switch that is what works the gauge(1 wire). The collant sensor is what sends a signal to the computer(2 wire).
