Wiring a backup camera monitor

[infinityknives]

I'm trying to hook up a reverse camera on my 2012 civic ex, but I don't plan on using the iMid screen. I was gonna drop in a powered rearview mirror which has an built-in screen that turns on whenever the reverse signal is applied. Does anyone know where one could tap into the wiring harnesses in the dashboard for the reverse signal?
