Welcome to Toyota Nation

You will need to specify the year and model of your Toyota, then go to the respective forum. I'm sure which ever forum it ends up to be-you will find the answers you seek. Good luck

its a '94 camry 24 valve and thats about all i know and he needs the one behind the cat replaced and cant firgure out where the wire is running to but someone told me he can just cut the wires and use a double end connector to wire the new one in so that he wont have to pull the wire and grommet out. any feedback appreciated nice site btw!!

Check out the Camry section for help.
But O2 sensors generally bolt into the exhaust manifold or downpipe somewhere and have a plug. Unplug, then unbolt the old
O2 sensor and plug the new one in. Then bolt it down. I recommend you change both gaskets too. I'll bet the sensor near the firewall will be a bit*h to get to. But I still recommend checking out the Camry section tho.
