I just had my new 02 sensor put in, however I can't find my sensor wire from the ecu. What color is your 02 sensor wire. DG's wire is brown and my wiring diagram book says it should be brown. I don't have a brown wire. I have a blue w/ black stripe, yellow w/ green stripe, a white wire w/ a big black coating, a white wire, and a white w/ black wire.
I thought that I had a 93 motor, but the wiring book I have is for a 93. What color 02 sensor wire do you guys have?

look at your old o2 sensor. is it a signle wire one or a multi wire.

mine is a single wire, i think brown or black, but thats just going off memory. i can look at it again for you probably tomorrow.

This doesn't have the color but its from a gen II 3sgte and has a notation to the O2 wire. Maybe it will be helpful.

wiring diagram

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.

I don't have the old sensor, i sold it with the old downpipe. All existing leftover plugs were cut, and the o2 sensor on accident. So I have a bunch of wires sticking out from there. I'm almost positive that the original sensor had only 1 wire. I looked at some of my old diagrams and then looked at the ecu plugs and think that the 02 wire is white on my car, which I have marked on my diagrams as ox1. I guess I'll give it a try tomorrow.
