just got my oxygen sensor.. how to install?

[SkylineDriven]

Ok I'm a super newbie and I tried the search already.... I have an S13 240SX and I just received my NGK/NTK oxygen sensor (with OE connector).... how do I replace this thing. I have no idea where the oxygen sensor even is located... can anyone post pictures and a writeup of how to remove the old one and replace with new one? Keep in mind that im a total N00b, so don't make any assumptions of what I do and don't know hehe. Thanks in advance.

Follow your exhaust manifold (metal pipes coming out of the motor where exhaust flows through, should be covered with a heatshield) down from the drivers side of the engine bay. You will see the O2 sensor sticking out of the manifold with a single wire leading up. That is your connector. To replace simply unplug that 1 connector (peel back the little rubber boot first) and use a wrench to loosen and remove the sensor. Not sure what size it is. It might be on there pretty tight too due to the heat binding it. To install do the reverse.
