2003 Accord EX 2.4L Air Fuel Ratio sensor wiring.
I have a 2003 Accord 2.4L 4 Cyl. I had a check engine light that said that the Air fuel ratio was bad or had a bad ground. I went under the car and it looks like the wires where pulled out of the plug that goes towards the engine. I have been trying to re-wire it see if it works. I have tried to find out where the 4 wires go. On the sensor there is 4 wires 2 Black, 1 Blue, 1 White. On the that goes to the engine the colors are Red, Red with a Yellow stripe, White with a Black stripe, and a Green. I am trying to put the wires back together but I dont want to short anything out.

The O2 Side was pulled out the Black White and Blue wires. Yes it is the one Pre-Cat. I am assuming that it is the primary O2 sensor. According to autozone its a oxygen sensor and an air fuel ratio sensor combined. Around 175$ for a new one. Trying to check and see if this one will work before I order a new one. They didnt have any on hand that I could look at for the wiring.

Are there two blue wires or just one.....so far I've figured out where two of the four go.
The other two, I know the wire color at the ECU/PCM but I'm pretty sure that color doesn't go all the way to the actual O2.
