The copy of the '92 Civic FSM that I have on hand has an illustration at the bottom of the LAF diagnostics page (11-42) that shows the positions of the different wire colors in the engine harness side of the connector. You should be able to match those up with the colors on the sensor connector, assuming you have an unmolested sensor handy.
I'd worry about the EGR stuff before the O2 sensor. often in odbII cars you can get several codes because of one failure. EGR malfunction could possibly affect o2 sensor readings (sending an o2 sensor code) but the opposite is highly unlikely.
