Hello all. I bought a used Captiva and noticed that the check engine light recently came on. It came up as a few different codes directing me to the o2 sensor. When I checked the downstream sensor, the o2 sensor wasn't even connected to anything. I could not find the connector coming from the vehicle and eventually noticed that the wires had been cut and there was no connector. I bought a new pigtail to put on but now cannot find a diagram to tell me which color wires go to which. I have a red w/ black stripe wire, tan w/ white stripe, gray w/ white stripe, and purple wires and don't know what they are. Can anyone help with a color wiring diagram or know which these wires connect to the sensor?
