It's the Powertrain Control Module. This module monitors and controls the alt. input and output signals and adjusts the field strengths. The thermistor is only a temp sensing fuse. If the current gets too high, it opens before frying wires, much like the smaller version in the blower motor resistor block. Unplug the PCM and check for any kind of pin damage or corrosion first before replacing it.
