Hey guys, I recently purchased a N1 exhaust and noticed that my catalytic converter was rusted, with all the screws and the bottom portion was rusted where it had a hole. I just recently bought a new cat. converter and tried to installed it, went great for a bit until the downstream o2 sensor would not unscrew. Spray penetrating fluid on it and left it sitting for abit and it still would not unscrew, stripped the nut so my brother told me to clip it off and just buy a new o2 sensor but I dont know where the downstream o2 sensor leads to. If anyone knows please tell me in the comments. It looks like it leads to the center console but I dont want to remove anything thing until i know where it is located. I tried looking around youtube and other forums but I cant seem to find anything. Thank you!

 

The connector for the secondary O2 sensor is located under the center console, next to the parking brake.

 

THANK YOU so much.
