ECM or ECU pinouts - Toyota Yaris Forums

I need to remove the backshells to see the wires (haven't figured that out yet, don't want to break them). Should they follow the 2007 color coding (which I have)?

How can you say that the "pins of the ECM don't agree..." when you have never looked at them?

When I remove the connectors and look at the pins, they are not the same number of rows as shown in the doc, and the number of pins per row is also different. I went through and logged each pin with ignition off and on, then tried to correlate it to the connector pin-signal drawing and couldn't get a correlation.
Sorry I was gone for a few days and am late in replying.

I just realized that you are not the original poster. The OP had a 2007. Your 2013 is a completely different ECM.

I found correct schematics on Mitchell DIY site.
