Sent you a PM but I'll also post it here for others' benefit...

Looks like the picture from Pugman is correct, based on the position of the O2 sensors, but double check the colors based on the second diagram, which is from the TSB. Reason being I've seen O2 sensors have their positions switched around for whatever reason, either by the owner or dealer, and so the "middle two" aren't always the secondaries.

The colors indicated in the TSB diagram refer to the color of the wire shroud under the heat wrap. You can sort of see the red of Bank 2 Sensor 2 in the photo. The other one should be white.

Hope this helps.

Let me know if you have more questions...
