I bought the PLX-250 because it seemed like a nice wideband and has a replacement for the stock narrow band.

I won't debate the need to keep or eliminate the O2 sensor. I just decided to keep mine, especially for emissions.

and I love this forum! There is so much info that I don't how anyone can't find something to help them with problems with this car....

from Lightening in the world of thunder:
http://www.fd3s.net/o2_sensor_install.html

it mentions the O2 sensor wire is 3C

in the FSM:


it shows the 3C connector location.

Can someone help me orient the picture in regards to the acutal connector so I get the right wire? Thanks.

best way to do it is...look at the diagram and get the color. See where the color is in the #3 connector, then go hunt it.

I'd get the color for you but my manual isn't in front of me.

The ECU diagram in the book is looking from the wiring harness side with the release tab at the top. I ALWAYS triple-check wire colors and positions before doing something.
