I do have a meter, but didn't bother, as there is nothing I can anyhow... the unit wont run. Just a thought, the obd2 connector I bought had a data/usb type connector on the end. I bet the stupid obd connector module takes it down to 5v. I already bought an 11 ft cigarette lighter to RJ11, but the run will be long.

12V Access: Model S 2021 Refresh

Yes, if your connector had a USB, it definitely has a step down built in, and should be at 5V. You may be able to remove it or tap into the wires before the step-down. Depends on the build, I guess.
I have an OBD connector without the step down. I intend to measure the V both while parked and while driving. I just need a car to test it on!
Are you aware of any switched 12V power in the trunk? I'm installing a tracker that needs both constant and switched power.
I haven't had a need to search for one. First place I would look is the power wire for the Subwoofer. That must be switched as there is no need for that to be powered when the car is off.
Update: My Escort 9500 gave a "High voltage" alert when I plugged it in. I added two diodes in series, and the voltage dropped to 13.7V, which gave me no errors. I drove around for a while too. The radar stayed functioning the entire time.
Update #2: I do not have the trailer hitch harness. At least not on the driver's side. If someone wants it, just DM me your address and I'll send it to you so you don't need a Model X or Y VIN to buy it.
These guys here. $7 for 20 of them. Just remember that the side with the white band blocks current completely if coming FROM that side. Reduces it slightly if current originates from the other side.
Some information about my radar install is here.
I just realized that I forgot to reference the radar install link. I’ve been driving around since yesterday with no hiccups on the radar function.

Nice Install on the radar. I know there's been some question on this thread (earlier on) whether the OBD on new refresh S/LR was now switched or under what scenarios the power dips. Can you confirm this is in fact switched now with your recent delivery?
Absolutely, positively, switched. All prior MS’s were unswitched

Does that mean that the Savvy product for the Valentine will work on the Refreshed Model S?

SAVVY serves as the power source for V1 Gen2, replacing the Lighter Adapter or the Direct-Wire Power Adapter. Plug SAVVY into your OBD diagnostic port.

The Savvy product doesn't work on the refreshed Model S. I tried on my plaid a few weeks ago and it wouldn't power on the radar detector.

I don't know for sure but I don't think it was a voltage issue since the cigarette lighter power source is also high (15.1V in my car) and that powered the V1 just fine.
Valentine1 states on their website that electric vehicles have an issue with SAVVY but I'm not sure what causes the issue. I tried a new SAVVY in my new S and it didn't work.

Love this install @KevinY ! Thanks for pointing me in the right direction on this. I added a 12v socket to my plaid last night. I have the exact same use case, a 12v fridge that we use on trips. I loved the 12v in my X, but I had been supplementing it with a small Jackery 300, since that 12v was switched. It will be nice to not need to carry a supplemental battery in a car full of batteries.
I just want to verify with you that this 12v line is indeed unswitched in your testing. The car has been charging since I finished adding the 12v socket, but I assume you've had plenty of time to verify that it does indeed stay live all the time? I set off on a long road trip tomorrow, or I would have spared you the lazy question.
