Default O2S Heater Circuit Codes

I just had LT headers installed and the car started throwing these codes:
P0161 O2S Heather Circuit Bank 2-Sensor2 Malfunction
P0141 O2S Heather Circuit Bank 1-Sensor2 Malfunction

I did a search but came up with no real answer to the problem. Since I have sims on the upper O2 sensors I'm guessing it's the back 2 sensors. Can y'all tell me what the fix is?

The sims belong on the rear O2's You need functioning front O2's for engine management.

I had it backwards. The sims are on the back O2 sensors. They won't plug into the front plugs.

Did you melt any wires with the new headers?

I have the LG Street Series with the HF Cats and X-Pipe. I put 02 sims in the rear and the only time I get codes is what I realy jump on it, otherwise no codes. I am getting ready to send my PCM to ECS for a tune which should solve the 02 code problem.

I turned off P0161 and P0141 O2 sensors with my programer this morning and haven't gotten any codes since. Put about 15 miles on it since.
