I am looking for Knock sensor wires on ECU
To get the read out on the knock sensors, I am looking for ECU Pinouts. What two pins are for knock sensors on ECU?

Don't go to the ECU, find the knock sensor plug and ohm it out. Also take a hammer to the block while you are on the pins and see if it generates some voltage, don't bang the crap out of it just small pinging hammering. Check both of them.

Knock Sensor 2 circuit high PO330
With engine running (using multimeter)check the reading bewteen PIN 1 and 28 and compare with 2 and 20.
My test showed that knock sensor 2(pin 2 and 20) was showing totally different reading consistantly then Knock sensor 1(pin 1 and 28), even when I knocked on the engine with a hammer (Gently).
Now after confirming that the problem is a BAD knock sensor since reading is not changing even when I knocked on the engine, instead of disassembling half of my engine to replace it, I just cut the wire of pin 2 (RED) and connected it to pin 1 (Black) on ECU side and cut pin 20(green) and connected it to Pin 28 (White) on ECU side. IT's plug E9 in the picture.
No more check engine light with error code PO330.
Please do it at your own risk, I am not responsible if you damage anything while attempting this.

instructions/diagram to access ECU on 2004 RX330
I'm trying to access the ECU behind the glove compartment to get a good view of the cable connections. I am getting a knock sensor code and wanted to check the connection and wiring on the ECU. What else besides the glove compartment do I need to remove?
