Vim3 in a car power questions

So i have 99% of what i need working, the one thing that i am trying to figure out is how i can hook up 3 wires

  1. power
  2. acc
  3. ground

to the vim3 this way when i turn the key off it will send a “sleep” or standby signal to the vim3. I found a device here but this works with raspberry pi and not sure if it will work for the vim3. Has anyone done something like this before?

Hello, Yes similar was done by @tschultz in his Truck dashboard project. Others on the forum, like @davemf have also done similar.
