SC430 ECU location?

Hi all,

I was searching the forums but I didnt see anything in reference to the stock ECU location? Can anyone help me... I need to find mine. Does anyone also know a link where I can find a wiring diagram for the factory ECU? I have to check my wiring from the computer to the bank 1, sensor 1, 02 sensor to make sure its not cut.

Thanks in advance!

And this for the locations of all the ECU in the multiplex communications system.

The engine ECU for the Lexus 2002 SC 430 is to be found under a cover in the engine compartment close to the driver side headlight. A child could remove it.
