Hi i bought a factory 02 sensor for my subaru liberty 06, it has an aftermarket plug on the ecu side i need to wire the aftermarket plug to the old plug of the old sensor. Just wondering if it matter if u mix up the heater circuit wires because they are the same color. thanks

I think it matters. And one more thing: Do not use aftermarket O2 sensors on your car.
