EV mode possible on Pruis (I)

Now that I introduced myself and car in the previous post. I wanted to throw out a question that I have found an answer in two evening of searches or YouTube videos.
I see and understand the seeming simple process of doing this mode on the Prius II however I'm not sure if there is a EV function pin on the early Prius I ECU. When I look at the connector pinout in the electrical manual, connector H14 pin 27 is located in a different location. In other word the pin layout is not the same as shown on http://www.eaa-phev.org/wiki/Prius_EV_Mode_Button

In fact if I look at connector H14, pin 27 in the wiring (block) diagram, it is designated as ETH- going to the engine control module, connector E9 pin 27. Not sure how all this relates to the Prius II ECU since that pin is vacant in OEM connector (pre EV mod).

I'm looking advice about the possibility of doing this simple EV mode mod if it is possible.

Thanks,

Steve
