Dash Wiring Harness Mystery Baby Round Connector

After checking with my multimeter two pins have continuity to the two spade connectors that are indicated as passenger door jamb switch. The third pin according to the wiring schematic is part of the Lights on Buzzer circuitry. I wonder if I have one of those still? Dash fire car seems to make me believe that is probably not good if it is still on the car lol.
