exhaust electrical wiring liberty gx 91

[Noodles]

Hello all

I have been doing some work on my 91 liberty non turbo single cam stock everything car.
I had a friend remove the exhaust and he accidentally broke some electrical wiring connecting to the exhaust, the wires have been pulled clean out of the connection cluster. I am fairly certain that this connection is some variety of exhaust sensor or substitute to a turbo pressure sensor.

I have recovered the tip and can reconnect the cluster without any issue I'm just not sure where each individual wire goes into the cluster tip. At the moment I'm thinking I could just match them color to color on each side of the cluster but I'm afraid that may reverse the polarity and possibly cause a short or ECU fault.

I have mocked up a diagram here

As you can see in the diagram there is a red, white and black connection exhaust side.
And a white/w black line, black w/ white line and red and yellow ECU side represented by stars on mock up.(the grey star is a viod, no connection)
If anyone can help me with connecting the wiring or a ECU output/input diagram it would be much appreciated.

O2 sensor, match them colour for colour and it'll be back to normal
