Spare TPMS switch for EV mod button?

So I've just done the EV mode mod. For the moment, I have a random momentary switch hanging off a piece of wire.

I'm considering the switch... I don't like the idea of doubling the cruise "cancel" button, as the Coastal Tech EV kit does. I don't care for the random momentary switches as done in the elearnaid.com kit, or the .pdf file I found on Prius Chat, as written by Evan Fusco.

I do have a spare TPMS switch from the junkyard. I haven't tested it to see if it's a "normally open" switch, but I believe it is.

(edit: having tested the spare TMPS switch, it is indeed normally open)

There's a spare cutout for it, right between the SKS and TPMS switches. That would put the EV button in a discreet, easy-to-reach location, but also render it impossible to hit by accident.

What say the hive mind of Prius Chat? Is this a good idea?

 

I'm having a tough time finding a switch I like for the factory location. The "proper" switch for a G2 (the one the rest of the world used) is either hard to find or ridiculously expensive.

The switch from the Prius C looks like it might fit. Or maybe not. There's no way of knowing, aside from buying one. Sadly, the switch cutout in a G2 Prius is different from every other switch used in every other Toyota, which makes me sad.

 

That's certainly worth a go, thanks for the idea!
