looking for help with my 2008 Silverado 1500. The 02 sensor for bank 1 sensor 2 code is in, and I have located the sensor and the plug that is not plugged into anything. I cannot find the other end of the plug that goes to the ECM. I have pulled back the sheath on the wiring harnesses in the vicinity but still cannot locate the other end of the wires(I assume the other end got pulled off) if some ne can help out with a wiring diagram or know where this ties into, it would be very much appreciated.


Thanks
