Another auto dimming mirror post/request

I've done a lot of searching forums with no success on this one. I'm trying to find a good source of power for the rear view mirror on my 2018 Tundra SR5 with bench seat. Every post I read says look above the overhead console and you will find plugs......not on this one. Any ideas on a good way to get switched and/or constant power here? I'm not concerned about a reverse interrupted feed like some use. Thanks in advance.
