Co2 wire broke off at end. Can't tell what color wires are in plug to rewire. Do you know which wire goes to which?

Are you referring to the oxygen sensor? Those wires can not be spliced or soldered on. Outside air travels along the wire inside the insulation and into the sensing element to be used as a reference to compare to the exhaust gas.
