Use voice command button for EV mod?

So I've been reading the threads about using the headlight flash switch for the EV mod and was considering doing it this weekend. But, I don't really like the fact that it means that the high beams will flash when I engage EV.

So, as I was driving home today, I noticed that Voice Command button on the steering wheel. The voice commands have got to be the most useless feature of the Prius, and I never use them.

So, could the voice command button be used to engage EV? Odds are that the button simply grounds some wire going through some connector when you push it. It would just require figuring out which wire and use it instead of the headlight flash wire.

Any thoughts?

 

Well, the wire(s) have to go through some connector that would be in the steering column (just like the flasher stalk wires do). Someone with the tech manuals should be able to identify it.

I might have to finally download those tech manuals.
