BT 5240 side mirror camera add

[Theockos]

We have a 2022 BT 5240 with velvac 2020 XG side mirrors that have the turn signal/marker lamp below the Blindspot convex mirror. I want to replace that with a Blindspot camera. After much searching and unable to find information, I was able to widen the hole to pull out the marker and the harness connector. Has anyone replaced this marker with a wireless camera using the power from these wires? I don’t want to run new power lines and new connectors. The two pin connector seems to be proprietary or very uncommon as I have checked auto parts, stores and online. Before I start to cut and splice, how has anyone added Blindspot camera systems without hard wiring power separately? The camera I want to attach also has two wires.

BUT what Control are these wired to and WHEN are they hot? and when does the power go off? re: driving vs storage/ phantom battery drain? Put a meter on them yet?
