ECT vs temp sending unit

[hytwr1]

What is the difference between the ECT and the temperature sending uint that drives the temp gauge? Or are they one in the same?

Thanks

ECT is the sensor that sends signal to the computer. The temp sending unit sends signal to the gauge. Two different animals.

Just wanted to be sure.

They are mounted next to each other. Correct?

Thanks

yes, side by side in the heater hose beneath the intake inlet.
