I figured out the wiring on the bosch site for the o2 sensor. The o2 has the two white ones as the heater, the black is ecu and the grey is ground.

When you mean return to ecu is that the same as ground? The two heater wires are swapable aparently as you said.

If I can get the last two wires sorted out I'm good to go and pass inspection. Thanks for all your help.

FYI I tried to search google but all I kept coming up with was how to install a logger. Which didn't help with the wiring colors (you would think it might!)

Maybe I can get the mitsu dealer to give me the info if I call tommorow. If So I'll post here I'm sure someone else had the same problem.

A link to a page that has info on the second gen o2 sensor on 1000faqs link is broken so that was of no use either.
