the car is a 94 LX (US Spec)
I know the O2 response is very poor at this time, so I want to change it. I work at an Automotive R&D facility and we have alot of O2 sensors laying around, so I can get one for free.
My question is: Has anyone wired up their one O2 sensor? If so, what is the proper wiring? Whithout looking at it, I am assuming it is a 4 wire heated O2 sensor, so I need to know what colors or numbers are the Heter supply and groung and the signal suply and ground? I can get a volt meter and figure it out, but since it's Friday, I thought I could get a little help in bypassing an hour or so of work on this car.

If anyone knows the wiring of the O2 sensor that would make my day!
OR, If there is a webpage with wire diagrams avaible, that would be great as well.



BTW, I am new here(first post) and I did a search and couldn't find what I was looking for, so if it has already been posted I'm sorry, and please direct me to the thread.

I went outside and looked at the O2 sensor.

The connector on the sensor is layed out like this:

White | White
_____________
Gray | Black


Hope this can help anyone that can help me out?
Is it diagonal paired or vertical paired?
