Welcome to TRS 
There are two
ECT sensor, only used by computer, 2 wires
ECT sender, only used by temp gauge in dash, 1 wire.
ECT = engine coolant temp
remove the larger air tube from air filter housing to upper intake manifold
ECT sensor AND sender will be located side by side just under upper intake where larger air tube connected.
Remember they are not the same, 1 wire = temp gauge, 2 wire = computer
