I just installed an o/r x pipe, but on the passenger side I can not find where to reattach the o2 sensor. By that I mean I have the actual sensor in the pipe, but the wire coming out of that has no where to plug into. Is it just short because of the removed cats? I have an xcal3 tuner, but the CEL keeps coming on cause of the missing connection. Does anyone have pics of the proper o2 set-up? A view under the car so I know where to hook it in?

No pick but when I installed my O/R X I had the same problem with the wires being too short. I had to spin the female end of the connector the opposit way to make it fit. It's mounted in the middle of the car on the left of your exhaust just keep lookin you should be able to find it.

One of the connections is on top of the transmission. I had to pull the connector from its plastic clip that held it to the transmission so the wires would reach.

+1, +1. It will be a blue connector, look on top of the tranny, it's held to a hole on top of the tranny with a one way push plug.

So do I need the extension or should it reach if I take it off the top of the tranny.

When i put on my o/r h pipe from pypes I had the MIL eliminators from brenspeed..But i had plenty of room without them. Are you talking about the top o2 sensor near the headers? That one is a pain the butt if you dont have skinny hands haha.

It should reach without the extensions if the plug is out of the clip

Ok, thanks for everyone's help! I'll check it out and hopefully it'll work.
