02 Sensor Wires

[STGGSX]

I have installed a 02 sensor simulator on a 99 gsx due to no cat, and i keep having the CEL coming on. I thought this was going to get rid of the light. I have wired it up and i want to make sure i put the wires on the right ones. Can someone tell me what wires are what on the 2nd 02 on a 99 GSX. I taped into them after the plug inside the car underneath the carpet. Thanks

For rear O2 red and yellow/black are the heaters (red is +12V). White is signal and black is signal ground.
