Electronic Mirror install for dash cam

Hi All, First post here. I have a 2007 Tundra SR5 double cab and I would like to install a dash cam. I would like to use one of the power splitters that gets power for the camera from the mirror connector (linked below). I have the basic mirror with no electronic features, If I buy a mirror with the compass and garage door features is there a connector in the headliner that I can connect it to? or are the cables not there for the mirror if it is not installed from the factory?

Yes I recall there is switched power and constant power in the forward part of the upper console. Unfortunately I can't find which wires, but they go into a harness.

I installed:

Welcome to the forum..

Maybe peel gently the headliner back and see if there is a connector.
Should look something like this..




Here is a wiring diagram for that connector.
