1.4 Petrol AUA O2 Sensor Testing

Hi,
Trying to get to the bottom of an Engine code and VCDS is pointing me to the O2 sensor. I have access to the front sensor one and the electrical socket and would like to know which pins to test to get the resistance across the heater circuit. Google is not helping much with the 6 pin sockets I am finding down there. Guessing that the thicker of the wires leading to the plug on the car side (white and grey) carry the heating current, leaving the thinner ones for the sensor element. All wires on the sensor side of the plug seem to be of the same thickness.

Pics are of both sides of wiring socket. Numbering on side does not match up between the two!

Can anybody confirm or help please?
