i really need your help with a small but different problem, this has to do with the Oxygen Sensors, and is proven very hard to follow the trail so, we are trying to put in new 02 sensors and we need the location of them and do the run in any special order?

Not sure what you're asking. What are you trying to solve? Which engine do you have? There will be two or four. One is ahead of each catalytic converter and one is after each one.

The front and rear sensors work the same way but they perform different functions. They can't be mixed up by switching plugs because the Engine Computer will think the readings are from the wrong side of the engine.
