The blue and grey wires are for the resistor that is normally mounted in the sensor side of the plug.

Perhaps the resistor has been removed from the plug and mounted in the harness on the car in question.

which wires do they go to on the harness side?the other three are color coded to each other but i do not have blue and grey on the harness side only on the 02 side

Sounds like you have one of the newer-style O2 sensors. the blue wire on the sensor goes to the orange wire in the harness, and the gray wire on the sensor goes to the red wire in the harness.
