No O2 reading

Ok I have been trying to have Tom remote tune my car, but we have run into a snag. My ecu is not getting a reading from my O2 sensor. I have replaced the sensor, checked the fuse, and checked for power at the plug. I can't find anything wrong.

Anyone have this problem or maybe someone has a diagram of the ecu pin out from an 04? I need to check there and see if its getting a signal.

I really need help with this quick. We can't work more on the tune till we know the reading and its affecting my idle.
