I have just installed my dash cam with this:

Do you also have a radar hooked up on to the mirror or just the dash cam?

First wire is power third wire is ground.
That's the way I had it wired before. That 3rd ground wire is the reverse one; you DO NOT want that one. The correct wires for my car (no ACC) were the 2 leftmost (when sitting on the car) on the mirror connector. When you turn it around to insert the wires from the back, they're the 2 rightmost wires. I had to address that issue when I noticed my LED reverse bulb partially lit when driving.

I think the wiring is different on a 2021 GT Premium with ACC. There's a video here that shows it.

I'm coming confused which ground should we use exactly to avoid the reverse issue😅?
What I understood from your description is these (yellow arrows)
