the wires that are the same are the heater. it doesn't matter which way they are connected in relation to each other.
the other two are the O2 sensor itself.
the stock OBD2 O2 has white as the positive side and light green as the negative side.
logically the green is the positive side and black is the negative but the only way to know for sure is to trace the wires.
the positive side should run to D14(O2 signal input) of the OBD1 ECU, the negative side should run to D22(sensor ground)
