lambda sensor need help

[Curtis Mcphail]

Hello guys n girls

Just trying to wire up a Denso lambda sensor to the rear position but am needing help on what wire goes where? The demos has 2 black 1white and 1 blue wires just need to know the corresponding wires? Any help would be massively appreciated

the 2 blacks are the heater wires and not polarity sensitive
the blue is signal to ecu
the white is the ground

whats the colors on the car ? or the other end of the plug your soldering in ?
