Rear View Mirror 10pin power pinout?

I want to install a dashcam and use the rear view mirror power to get both the 12V with the car off for parking mode, and 12V ACC for normal mode. Does anyone have the full pinout? I looked into the Dongar adapter but it only has one USB plug so that would either be powered on with ACC or all the time. From probing that connector I found the top left (viewed from back) is 12V constant power and couldn't find one that was powered with ACC. Seems like a dashcam which just uses this 12v constant power without a dedicated parking mode is going to drain the battery. The Fitcamx has a similar looking connector but it has an 8pin output which could possibly have both. Does anyone have the pinout?
