12V Accessory Circuit connection?

[Robotpedlr]

It did work, but not as switched. It was always on. I ended up connecting to the USB power wire that runs through the console as some others on here have posted.

coming late here, so what is the consensus here ?
I wish to hardwire a radar detector, what is the best place that is easy & convenient to get to and has power only when car is on ?

You can order this cable off of Amazon for $5. It is a perfect fit. Just cut the end off that you dont need and use the wires to connect your power. If I remember correctly, the red wire from the new plug will connect to the ground for your camera (which is black) and the blue wire from the new plug will go to the Red of your camera (which is the power).

where does this connect to ? is it switched 12V supply

12v wire tap for Radar Detector
is t his it ? but need the same for model S

I ended up using the connection referenced earlier in this thread. I used the standard escort hardwire kit:

Positapped the switched +12V from this thread and then put the ground wire under a nearby ground lug. Wires were the perfect length.

thanks for replying
which one did you tap ? did u mean the one by removing the passenger side panel and red wire with white stripe as in post number 5 in this thread ?
also did you have to use a harness to tap from that connector ?

There is an unused plug that sits under the small panel behind your mirror (the small cover that snaps out). It is not switched (always hot) so good for a camera but probably not a radar detector.

thanks for your reply. Yeah not a good place to tap for RD. I ll wait for better place to tap

Hopefully these help... red with white stripe is spare +12v, black wires on end of connector is ground.

I know about the other 12V sources; Tesla specifically says that they recommend using this circuit for 3rd party accessories (while also disclaiming any liability..)

We don't know how much load we can put on the other 12v sources, nor do we know what else is on there. This, as far as I can tell, is a dedicated circuit.

I'll see if I can't source the connectors and make an adapter. Am also curious where this circuit actually ends (as it appears it may be passed through this connector?)

I found the same connector on my 2018 Model X (same location, similar plug), but it has less wires than the one in your pictures. Also, I could not find any switched power anywhere on the adapter

Can you take a photo of yours? Should be the same wire colors... Red with white stripe is switch +12V and black (on the other side of the connector) is GND (or just use a close by ground lug like I did). I ended up positapping my red/white wire.

 

[jordanthompson]

I did find the white/red wire, but it always has 12v present (even after closing the door and locking the car.)

View attachment 388071 View attachment 388072 View attachment 388079 View attachment 388082 I did find the white/red wire, but it always has 12v present (even after closing the door and locking the car.)

If you’re metering the white/red wire it should definitely be switched.

If your IC says “car off” and not R P N D, in my experience it usually shuts off when the drivers door gets closed after the driver exits the vehicle (and turns back on when the door is opened).

It’s all controlled by the MCU though, so it could turn the accessory rail on at any time (IME, it does when downloading updates for example)

 

[jordanthompson]

You are absolutely right! I just didn't wait long enough for the power to switch off (two minutes). Thanks very much for your help

Wow, I am learning so much about the car.

So there are at least 4 power sources I imagine from what I have read.

1: Switched power, turns on when you open the door, and off after about two minutes of exiting the car
2: Switched power, turns off when the car goes into deep-sleep, resets finicky devices by cycling off between drives
3: Always on power, to monitor for keycard to unlock door, potentially other stuff
4: Direct to the 12v Battery

Are there more? Does charging do anything other than delay deep-sleep, or are we at another level of power. Would be nice to know each of these as people identify places to tap power from the car. Like can I tap the 220v when I am plugged into an AC charger and feed that to my scooter's charger so everything charges at the same time? That would be another power source.

Recently learned a way to get the car into deep-sleep in 15 minutes to reset my charge port that claimed to need service. Would be nice to have an LED on the dash that shows when the various levels of power turn on and off so you can be sure what the car is thinking. Perhaps a light to show the car is feeding the 12v side thru the DC-DC converter.

Oh, and one for when the AC compressor kicks in like other cars have, although that could probably be added to the main display in software if Tesla thought it was useful.

Well, now that you mention it .. I did find one the turns off as soon as you lock the car (I thought I had a eureka moment!) but turns out it also shuts off when you put the car in gear (!) and at other unknown times

I just scanned through this thread and it seems to all deal with a power connection inside the car.

I am playing with the idea of installing a power inverter in the frunk. I believe there is another fuse box located up there.

Does anyone know if that is accurate?
And it so, is there an empty accessory circuit one could make use of?

Reviving this thread since Blackvue came out with the new DR900X which requires updating the power harness with a new one that includes a switched line to detect parking mode. My options are to add add a fuse to the fuse panel at F202 or tap into the red/white stripe wire on the passenger side console discussed up in this thread. Is the red/white stripe wire fused and what number is it on the fuse box? F202 is the 12v outlet on the front console, so does it have the same behavior as the red/white stripe and shut down after two minutes? I have a Blackvue 4 channel setup and pulling always on power from the doors. What do you think? Add a fuse to F202 or tap the red/white stripe wire? And if I tap red/white stripe wire where is fused for future reference? Thanks in advance!
