o2 Sensor Wiring Help

[— kung fu jesus —]

I would love to help, but I don't know what year the car is.

Just from knowing the year, I could go here.

Then I could find the O2 wiring diagram to see which wire goes where and probably figure out which wire does what.

On a four wire O2, one wire is a signal wire for the O2 (5v, I think), one wire is a switched 12v heater wire. The other two are grounds.

There should also be a wiring diagram that comes with a universal O2 like you bought to help with the wiring.

I hope this isn't reading satirical, I really am trying to help, but you aren't helping yourself without giving the info people need to help YOU.

It's a 2000 :-) I forgot to add the year :-( Never even realized that different years probably had different colored wires.

Cool!

Most universal O2 sensors come with a weatherpack-type connector to splice in the harness. There should also be a wiring diagram with it that describes which wire on the O2 does (signal, ground, power). Do you have that? From that I can tell you which wire corresponds with your car's wiring harness.

On the wiring diagram for your car on the site linked above the wires on the car's harness reads:

RED wire -> 3J on ECU
BLK/RED -> +
RED/YLW ->3V on ECU
BLK/WHT -> GND
