the switch used to engage EV mode, does it simply short pin 27 on HV ECU with ground on the vehicle?

Yes. To clarify, it is a momentary ground provided by a momentary switch. So, you could add your own switch like I did, get an imported OEM switch, redirect a grounding contact used for flashing the brights on the combo switch, or use Coastal's mod that adds this function to the CC cancel.
Or, dream up your own idea!

its possible

Wow, very simple concept. I cant believe this, well sorry. I just see so many people buying the EV switch and it simply just shorts HV ECU pin 27 to ground. I cant wait to get my salvaged prius running. I have so many switches laying around im going to get a nice one for this project. Cant wait!

prius

this is irrelevant but i had my salvage prius and my HV battery was discharged, i knew there were chargers out there at dealers. So i visited some big guy that had that bully persona at toyota, he was the "prius tech" ( i put it in quotes because well hes not even close ), so i asked if there was a HV charger he said no you need to replace HV battery. Therefore i left, and went on my journey to create a HV charger in a chock full of nuts can.
