It would help if you gave us WHICH O2 sensor you are looking for the wire colors of?

But if by chance this is Bank 1 sensor 2, then C196:

Pin#
1 391 (RD/YE) Voltage supplied in Start and Run (overload protected)
2 389 (WH/BK) Heated Oxygen Sensor (HO2S) #12 (9G444), heater
3 359 (GY/RD) signal, return
4 392 (RD/LG) Heated Oxygen Sensor (HO2S) #12 (9G444), input

Here's a replacement connector so that you can perform the repair right.
