So funny how ridiculous things are sometimes I thought I bought the right o2 sensor but instead of the 97-03 upstream sensor it is for the 04^ upstream. Now its the same square plug bit instead of only having one tab on the plug it has one on each side. Now I'm really not looking forward to sending back because its literally the same sensor it just has a different plug on it so couldn't I just theoretically cut my old plug off and attach it to the new sensor so it fits in my o2 extension properly so I dont have to send back? I dont care about cuttin wires and using some connectors to reattach that's no big deal
