I am replacing the downstream O2 sensor. The wiring harness on the car is missing. I need a wiring diagram to know what wires to match the wires on the new sensor to.

Sure, here are the engine wiring diagrams which include the oxygen sensor wiring. I have also included a guide to help you check the connection once the repair is complete.
