ECU pinout, anyone?

[geog1]

Disconnected (pos & neg), then charged battery in car. 

Now getting p1600.

Can someone tell me the correct ECU wire to test for 12v?

thank you

What I saw on the net for both Toyota and Lexus was "check EFI fuse first".

Here's a diagram. 

Hope it helps

Thanks for getting back to me.  

I checked every damn fuse I could find.

What I wanted to verify, is the where (connector pin) of the B-Y  16 (E5).

If the B-Y holds true for me, that may be useful.

Haven't found 12v anywhere, yet.
