    I found the video quite clear on the location of the components and the procedure /tools to replace.

    If you do not even know what the sensors/converters look like you need to know how to do this properly which I find hard to believe you would know how to do this ,,, but not know what the parts are.

    as you saw the connector takes the longest amount of time. this if you screw it up will cause problems , failure codes. these wires are not to be changed soldered or altered in any way as this will throw off the O2 sensor extremely low voltage that reports to the PCM.
