So far it does not look like it. At least not a conventional fuse box that we can use for power taps. Even looking through the parts catalog there is nothing resembling a fuse box or fuses.

Has anyone installed a radar detector in a updated 2021 model S?

Well, that sucks for people who like to mod their cars like me. I have blown a couple of fuses in the past.
I asked this a couple of weeks ago: is there an OBD port somewhere? I heard on the M3 that it was in the rear, below a vent or something (to be honest, I didn't really research). On my current 2018 MS, I use an adapter to get 12V power to my radar.
FYI, I am using an installed radar detector, and love it. The radar sensor is behind the bumper and I get no signal issues. As far as power goes, I want a clean install, with zero visible cables.

Confirmed with service. No fuses in the refresh Model S.
So far it seems that the only reliable way is through the 12v plug or the wire feeding it. I'm sure others will be discovered but that is it until then. Tapping a monitored wire will cause alerts. Hopefully this thread will collect discoveries of other safe wires.

Try using Tesla Waze on your main screen browser for identifying speed traps and police locations... I have found it to be better than my V-1 radar detector.

Maybe in California Waze is better. But on rural, less traveled roads, you are likely to be the first to encounter, or the first to report a speed trap. I have never gotten a speeding ticket with my Valentine One powered on, and that is for 40 years, so Waze could never be better than that, in any environment.
You are correct. Even in California, we have rural roads. Waze works off crowd-sourced data. If there are no crowds, there is no data. The advantage of using Waze on a smartphone, is that you can see how many wazers there are online. I typically turn that feature off, as the screen gets cluttered. I turn it back on when on rural roads. If there is no one online, I just shut it down and no it will not give me any good data. One of the benefits of Waze for Tesla, is that it shows speed traps.Maybe in California Waze is better.

To be honest, as a have grown older, I rarely find myself in a situation where I am speeding too much. I push it only a tiny bit. I have been hit by a radar gun many times, and they never stop me. They are typically looking for more blatant violators. Still, I use the radar to keep myself in check, and not rock the boat.

I can confirm this is the case. I ran a tap on a 12V wire I found and it set off a lot of concerning alerts. Good news is they went away when I removed the tap. Best solution is to go to the 12V accessory plug at this point.
S**t. I am not happy about this. I have always tapped wires on my previous MS's, without issue. I have a lighted T for the front, and tapped the headlight harness for that. I added trunk lights too. Again, one of you that has your refresh MS needs to search for the OBD port. It is somewhere.
What is the 12V battery in the refresh? I heard it changed. Can this be accesses somehow?

With almost 40 million people in California, I have never had a shortage of crowd-sourced data available in rural areas.
Tesla Waze provides amazing situational awareness before entering a speed trap... try it in combination with your radar detector.
Getting to and tapping the wire in the console is the hardest part. Run the wire under passenger dash, through right kick panel, up the "A" pillar , and across the headliner as far as you need. That is easy.
I am on MCU2 (late 2018). Still freezes everything too many times to make it worth it. Too bad, because I otherwise think it’s awesome.Are you running MCU1? Tesla Waze works flawlessly on MCU2.
395 between LA and Mammoth can be filled with drivers, or devoid, depending on the time and day.With almost 40 million people in California, I have never had a shortage of crowd-sourced data available in rural areas.

And yes, the best use of these items is to use all of them together. Even better if you have someone driving fast in front of you to “plow the road”.
Awesome!! I don’t have my car yet, but that sounds super easy. I might even just use a cigarette lighter adapter and plug my old hardwire harness into that if it’s that complicated. But it sounds pretty easy! Thanks!
