Frameless rearview mirror upgrade

The first mod for my Palisade is swapping the old bulky light-less mirror for a new frameless with compass and HomeLink indicator.
Almost plug and play except for the wires on the new mirror need to re-arrange to match the factory harness. 10 minutes job.

On the factory harness, there are 4 wires coming to the socket: ground, constant, switched and reverse. On the mirror harness/plug, remove the constant wire and connect that wire to the switched wire will disable Homelink when the vehicle ignition off. You'll have to mod this with either OEM mirror or upgrade frameless mirror.

I've been using dashcam for the last 7 years, had Lukas, Finevue, Garmin and a few cheap ones but they've all failed both hardware and/or software. I also had 3 other Blackvue dashcams on my vehicle and found them well build and features rich. They are pricey but I wouldn't want anything less.
so i can disable homelink when car is off w the OEM mirror.
How do I know which wire is the ground, constant, switched, reverse?
SO I need to splice the constant wire to switched wire and then put back into harness?

The picture shows the factory harness with 4 wires: Red is constant.Green is switched.
I would suggest leave that harness intact. On the mirror harness/plug remove or cut off whatever wire connect to the red side and tap it to whatever wire connect to the green side then your HomeLink will not working if ignition off.

Using a plastic panel remover or flat head screwdriver and gently pry off the middle section of the cover behind the mirror then you'll have access to mirror harness. You can start at the gap between the headliner and the plastic cover. It'll come out easy.

Thanks for the info. We have a white limited and I am bummed about some of the silly things they didn't do, like not backlighting the buttons on the mirror. Tell me, were you able to discern whether or not the buttons are capable of lighting on the original, but perhaps not wired? I have a 2015 Genesis and the mirror lights on that. A used one on Ebay is only 40 dollars. Maybe it can be switched out.

Green wire in mirror harness connects to Red wire (constant) in factory roof harness, White wire in mirror harness connects to Green wire (switched) in factory roof harness.
About to cut the green wire in the mirror harness and splice into the white wire in mirror harness. This should work right guys?
