    Unfortunately while removing the intake manifold to replace the starter, I broke a clip on the wiring harness. Does anyone know what that connector is for or what the part is so I can replace it? My best guess is ECT sensor?

    1 wire only is the cluster/gauge temp sensor.

    The 2 wire above it is the Engine/ECT sensor.

    @assassin10000 is right about the sensors. Don't buy aftermarket on this. Your gauge might not read right. Not sure exactly what to tell you on the broken connector though.
    @Tundra2 has pics of the part numbers for both sensors. Let me see if I can find them.
    Edit: got them

    If your wires and pins are in good shape you can buy just the new plastic connector at your local dealer and snap the pins into it
