How Is Your EV Button Wired?

Can one of you intrepid Prius Classic owners tell me how many wires does your EV button have and where do they go? In the US there is just a blank cover where the button should go and I would like to fix this.

¿Puede uno de usted los dueños clásicos intrépidos de Prius decir me cuántos alambres hacen su botón de EV tener y donde va? En los E.E.U.U. hay justo una cubierta en blanco donde el botón debe ir y quisiera fijar esto.

 

I had the impression that the EV button was standard on prius classics sold abroad, but that for reasons unknown Toyota removed the button and associated wiring from vehicles made for the north american market, leaving us with nothing but a cover plate where the switch should go.

If this is correct, then there should be lots of Pri classics out there with the EV button, but essentially none of them should be in the US. My hope in posting this message was to locate a non-USAn Pri classic owner and find out how their button is wired.

There seem to be a number of carry-overs between the different Pri's. For example, they are all ready for cruise control and the nav system, even if it's not installed.

If the EV button is a standard feature everywhere else then perhaps it is an easy mod to put it back in a US model - if you know what to do. Toyota even has a special switch for the function, which implies that it is common and normal, although not here.

Somebody, somewhere, figured out that it is possible to add an EV button to the '04. What they did was bring out an existing feature that is designed into the car. If I can find out what they did perhaps I can be the first to restore this function on a north american '01 model Pri.
