Downstream O2 sensor wire broke
The wire that connects to my downstream O2 sensor got pulled on and must have broke somewhere inside the wiring harness. I want to connect a new wire to the sensor and run it to the ECM. Just need to know which connector and pin on the ECM is the downstream O2 sensor
