Default 2000 ES300 ECU Pinout

Anybody know where I can find the ECU Pinout for a es300?
I've got the P0330 code, I was going to do this hack for now until I have enough time to fix it

Still need some help.
I was able to find a wiring diagram from a 1997 ES300, but it is not the same.

That website seems to be pretty buggy. I have tried to register, a few times, using different browsers. Each time it I fill out the "personal information" page and hit continue, it just reloads the "personal information" page. Can't get past it.
Anyone use them recently?

From what I've heard, TIS works best on internet explorer, unless you're looking at EWD for 2006 and newer as that requires additional plugins that are buggy and works better in mozilla.

I did some searching around for you and I think I found what you're looking for.
I will admit I'm not sure if this is all you need as I didn't look at the linked thread.

1997 ES300 Below

Wow, thanks for helping me out!
But.....that's the same information I have. The E7 - E10 connectors going into the ECM that are shown in the diagrams are different from what I have. All my connecters have 3 wires in the vertical direction, that wiring diagram shows 4.
I will try TIS with IE, that is the only browser I did not try.

I apologize, at first glance for whatever reason I looked up a 97 ES300. I just looked again and it is like you described with 3 vertical wires. I will leave the previous post up for those with a '97. Below is a 2000 ES.

Holy crap, THANK YOU!!!
That seems to be exactly what I am looking for. It shows the 5 harnesses going into the ECM, and the harnesses seem to have the same configuration as mine.

Thanks again!
I've been searching for days for that diagram. Did you find it on TIS?

Would be happy to help. What exactly are you trying to do? I can't post the entire thing up so if you would like to narrow it down for me I can try and post what you need. And mention the year of your ES.
