Buick Regal Rearview Mirror Connector Pinout

[Regal_GS]

I have a 2015 Regal T, and I am trying to hardwire a radar detector to the rearview mirror. I poked around with a multimeter, and I'm confident that I found the ground pin. Beyond that, the highest voltage I was able to find was only 10V, and most radar detectors and dashcams require 12V. I'm concerned that the Regal might not have a 12V source there and I hope that isn't the case. I have been unable to find the schematic for any of the connectors under the fascia containing all of the wiring, and I was wondering if anyone had any knowledge on the subject. I found some info for the Encore, but it doesn't seem to be the same between models. For context, my specific mirror is the Gentex gntx-860 from factory (I was told that the pinouts can change even within the same model year).

Thanks

I figured it out, and leaving the pictures here for anyone else with this generation of Regal looking to do the same.



Note that this is the top of the connector. These pins are the ground and the Switched +12V IGN pins. This pin will only be powered if the car is on, so it won't drain your battery while you're away.
