Save yourself the risk and trouble to get figure it out. Just use this. Its been years now, but it took us a while to figure out the source.
Teslatap made it easy. Dashcam Power Cable – TeslaTap
I have the 2016 (actually 2016.5 w/facelift) and it doesn't have the dash cam or sentry mode. Do you know if this harness tap will still work?

Yes, we sourced those parts and installed the first Blackvue's in 2014. I had them on me 2013 and on my 2017.

Took a while to id everything as there was no help from Tesla. Lots of people were using a 4 pin doggle that connected for power to a computer fan, but it didn't secure/fit properly.

A little history for you. This connector has nothing to do with TeslaCam mode.. The connector is for an an intrusion detection device that was required available in EU, then made available in the U.S. Sentry is watching the outside of the car. Intrusion Detection was when movement inside the car was triggered. Even so far as breaking glass and motion created when someone got in, stuck their hand in and started grabbing stuff.

But that cable is for permanent +12V supply, which is what you want for a dashcam so it records while parked. Radar detector probably shouldn't be permanently powered.

I followed the instructions here: R7 Visor Clip

I also cut off the duckbill portion that went into the headliner so it was just a straight piece of metal. The fitment is too tight and I couldn't get the duckbill portion in there. The straight cut piece does fit.

Additionally, I cut off a portion of the bracket that covers the release button on the R7.
What is the process for removing the plastic cover for the rearview mirror to access the wiring? I don't want to break it....

So I have a 2016.5 P90DL and my wire colors were a bit different but this thread was helpful. For me, the 12v switchable power was the red wire w/yellow stripe and the ground was the solid black wire (see photos). For now I am stuck using the suction cup until Blendmount or someone comes up with a better solution. Open to alternative mounting suggestions if anyone has any? (Please post photos of your radar detector mount set up in your Model S)

Here are some photos from my install/tap:

So, I tried doing the same... cut off duck bill skimmed a bit off the center part that inserts into the R7. I just couldn't get it in a position clipped to the headliner where it wasn't flimsy or flopping around where along the headliner did you secure yours? Can you post a photo?

All state police cruisers have different versions of the Spectre RDD (radar detector detector) as they are primarily meant to find CDL drivers breaking the law. All the Spectre needs is for your radar detector to be connected to power and emit RF signals, even the best shielded units will emit enough to allow the cop to know you have one once he/she pulls behind your bumper, maximizing your chances to get a ticket being perceived as a "subversive". Just sayin'

Not sure where you are from or what your point is but they are completely legal here.

I will try. It definitely isn't perfect. It does move around more than I want but, without a blendmount option and without wanting it to be on the windshield, this is the best way to go. I have a blendmount in my NSX and it is amazing. As for the Tesla, I get the best result by wedging it behind the driver's visor in the closed position. I can't really use the driver's visor which is annoying but having the R7 along for the ride makes it worthwhile.
