Hi,
The pressure switch is internal and only has two wires. The connector you have has seven pins. The only thing I can think of is that it is for the different shift solenoids and the temperature sensor inside the transmission.
Do me a favor. I attached the wiring schematic below for the transmission. Note there are seven wires going to the transmission. See if the colors indicated in the pic are the same as the wiring to the connector you have.
Let me know.

See pics below.
Update. I found it. It is part of the transmission wiring harness and is for what I mentioned above. It took some digging, but I found the harness online. Take a look at pic 3. That is on Amazon.
