DIY Knock Senor replacement

Hi guys! I am buying my friends '99 RX300 and his CEL is on. He took it to Autozone and they told him it was a knock sensor that needs replacement. From my search i know that there are 2 knock sensors also known as Bank1 and Bank2 sensor if i am not mistaken. I am going to check the wiring before replacing. i told him to send the code. I have done a search on the threads but come up short on DIY. My question is does anyone have any pics on location (written also) and how to change them?????? Any help you guys can give me would be great. Thanks guys

big job. the two sensors are located under the intake manifold. replace the wiring harness if you are changing the sensors, it will be brittle and you have to take of the manifold again.
