Where are knock sensors in my 99 Lexus RX 300 ?

There are two knocksensors in the engine of the 99 Lexus RX 300. They screw into the engine and have electrical connections at the opposite end from the engine, like a temp or oil pressure sensor, but I cannot locate them in the crowded engine compartment. Where are they located. Please be very specific.

I recently changed both knock sensors and wiring harness on my 99 Lexus rx 300! I purchased the parts on ebay and they state (OEM PARTS) Check engine, P0330,

code p 0330 refers to knock sensor (KS)2 bank 2 ---circuit malfunction===causes wiring--KS---ECM
it is possible that in changing the harness there is a problem connection or the connection to ks2 is not correct ( not on properly)
