Sorry for bringing up an old thread, but I am tackling a different project and wanted to know if the OBD2 power is switched, or does it keep the camera on 24/7?

OBD2 pin 16 is 12 volt, always on.

But the various versions of rear view cameras are drawing power from a harness interconnect that interjects into a native OEM section of harness, some pulling power from the front windshield camera power source and others from the passenger footwell area.

I use the OBD2 to power my radar detector solely during road trips.

I hope this info is helpful for your project.

Thank you, I currently am tapping to the 12v by the PRND on the roof, I've just been having issues with the e-fuse tripping in hot weather. Not really sure what causes it, but I am able to reset the fuse by unplugging the digital mirror and power cycling the truck, which is not something I enjoy doing due to having to take apart the whole camera assembly to reach the plug.

I was thinking about wiring a relay that is triggered by a switched 12v source and would power on/off the 48v stepdown I have in the frunk. This way I don't have my 12v accessories running all the time and I have a more reliable source of power coming from the power feed without having to toggle it on/off each time I get in/out of the truck.

I've seen some people also tap into the harness on the passenger kickpanel, but I'd want to try something less invasive first since that also seems to cause issues with the audio system.

I did an install of the TesStudio S92 camera by side-tapping into the front windshield camera power feed. The rearview would only turn off when the truck’s cameras turned off. So they would cycle on whenever sentry mode came on.

For different 12v applications I installed an Auxbeam 4 switch unit to the frunk’s accessory feed and I’m using that to keep a Bluetti battery charged, and then I feed my center console fridge off the Bluetti.

The Auxbeam 4 switch panel that I bought is 50% off right now.

There are various ways to mount it in the cabin.

The photo shows my installed switch panel.

To direct my comments at what you are possibly wiring up, I think pin 8 in the obd2 is only “on” when the truck has been turned “on.” You could test this quickly with a volt meter. (My truck is at the service center getting terrestrial armor.)
