Codes 2c3d 2ca6 2caa oxygen sensor help

My car has started throwing 3 codes

2c3d oxygen sensor before catalytic converter line fault
2ca6 oxygen sensor heater before catalytic converter function
2caa oxygen sensor before catalytic converter temperature

I am trying to test the o2 heaters but I donít have a wiring diagram or know what color is what

Anybody have a diagram?

Anyone else have same codes and replacing the sensor fix it?

It doesnt say bank 1 or bank 2 so i assume the heaters are wired together then the dme?
