P0030 and p0130 faults ….5 wire O2 sensor not 6 wire

Hi this is my first post, I am having a P0030 and P0130 fault code come up with occasional engine light.
I have a 2.2 Diesel engine. I have replaced the o2 pre cat sensor with a brand new one with the same fault codes.
I have checked the wires from o2 sensor connector break to ECU and they all pin out correctly ie connected and also I have +12vdc on the heater. So it all looks good.

When I checked the connector break to lambda I noticed it has 5 wires, where as on the other side of the connector ie connector break to ECU it has 6 and they all pin out to the ECU.

So is my 5 wire o2 sensor the correct one or should it be a 6 wire one, hence it flagging up a P code.

I am sure my old O2 and the replacement both have 6 pins but only 5 wires
