Help please
i have an 2005 rx8 and need someone to help me with the wiring of the upstream O2 sensor. I had to cut it off from the car’s wiring harness connector and I don’t know how to wire it back together. Please help me out
What am I doing here?

First, stop using generic, non-descriptive thread titles.
Which side of the connector did you cut the cable on?
If it's the side closest to the sensor, just get a new sensor. The last thing you want is anything that might give erroneous readings of the air/fuel mixture.
If it's the wiring harness side... whoo boy, you're in a pickle. I've been told that you don't want to solder O2 sensor wiring. Not really sure why but you're going to need a strong mechanical splice of some kind. Aside from that, here is a thread with the wiring diagram.

It’s on the actual wiring harness on the car. I cut off the harness conector from the car bcs it looked burnt. Whenever I cut it off the black electrical tape was pretty burnt on the car side. I the connector was kinda ok. There are two black wires a blue and a white on the actual O2 sensor. But on the car there’s 4 red and yellow wires held together with a coupler. Then there’s a blue and yellow wire, a pink and a purple. But there a non colored wire on the same spot as the pink and purple. That’s the one I don’t know where it goes... I’d send u a pic but I don’t know how to attach it to this reply
You can upload the pictures to Flikr, Photobucket, Dropbox or Google Picasa, or anything like that, and then just post a link here.
I may be missing the obvious, but do you not still have the connector and can't you solder it back on following the colours coming out of it? Or get another connector from a junkyard RX8 that should have the same colours?
The 2nd post in this thread has the colour diagram for the front O2 sensor. But it lists fewer wires than you have going on, by the sound of it.

Out of the S2 wiring manual, but I checked with the S1 wiring manual Team posted and they are identical
The thing on the right is the preheater, the thing on the left is the sensor unit itself.
