Uplug the the sensors wires and take a 7/8 wrench (I think) and unscrew from the exhaust pipe. Are they the front's or rears, Theres 4 if you didn't know

Just follow the wire until you reach a weather pack connector (shouldn't be much more than a foot) then disconect it. Unscrew the sensor out of the header and put the new one in and re-connect the connector. It doesn't really get much more detailed, it's easy to do.

If you can see the 02 in the header follow the wire up by the trans they probly tied up the wire. You will see a black/blue plug with a little tab, pull out on the tab and slide it out of the connection.

In this picture you can see the connector I'm talking about on the back pass. 02 sensor. It is hanging on the cross brace. If you look close it's black with a little blue thing.
