Diagnostic Port Index

So I spoke with the people at gpstrackingamerica. They said their shipping price is high because they primarily sell to businesses and with higher quantities. They ship out of Vegas and Canada but the shipping cost is the same because they use only ship with FedEx, ups, or puralator.

I asked about the 2019 cable and they said it's available now.

I placed and order for a 19 harness. These guys now have $9.99 flat shipping rate. I guess they saw our feedback.

I'm searching for the Model X 2016 adapter... anyone know where I can source a completed cable?

I got mine from Maxwell Auto Technologies:

I am getting a 2020 model 3 soon. I am curious to see if there are any changes in the port like how 2018 and 2019 are different. I might just get the 2019 adapter to find out if that works.

 

[Krash]

2020 Model 3 cable should be the same as 2019. No one has reported any changes.

Yeah I emailed GPS tracking America and they confirmed that it was the same.

FYI, these guys claim US (new york), but ship from Canada (according the person chatting me on the chat window) and have crazy shipping prices...

$30 cable and $27 shipping cost! crazy...

That is not what I was charged. I was charged $24.54. See below:

Thanks for your explanation. We were happy with the product. It was high quality and I recommended it on this and other forums. (P.S. As I recall, the amount on the UPS package I received was for shipping was a lot less than the $24.54 you charged <wink>).

Hello, this is very cool and I want to try it on my car.

Does anyone have a feel of whether there is any risk of voiding the warranty if Tesla finds out this CAN sniffing is being done...? Or upsetting Tesla in another way? What is their general feel on this activity?

I've never heard of a problem. I take mine out or just unplug the OBDII adapter and leave the cable and everything there when I take it in for service.

Aside: On our Chevrolet Volts there have been cases where On-Star has trouble communicating with your car when you have an OBDII adapter plugged in. I've had that happen as well and OnStar was able to talk to the car (read error codes) after I unplugged it.

Maybe this isnt the right place to ask but I am wondering who is working on hacking MCU2. It really sucks that we have a car that cannot be serviced by anyone other than Tesla. It sounds like MCU1 has been hacked but not 2. Is someone out there close to cracking it?

I ordered an OBD adapter for my 3 yesterday, and it's apparently shipping out of Toronto even though I'm in California - guess it's not available at their Vegas warehouse.

Hi I don't think the BLE module described above does not work.

Has anyone discovered if the OBD2 connector fitted to the Model 3 offers a permanent power supply?

This would then be a clean way of tapping the bus with existing connectors, for example to provide power for dash cams in Parking Mode.

The Model 3 doesn't have an OBD port. You have to tap into the main loom at the rear of the centre console with a special cable to be able to plug in an OBD/BT adaptor. You might then be able to take power from that but there are probably less messy ways to get power for a dashcam.

This video shows that you may need to tap directly into the 12v battery as most of the diagnostic access points go to sleep.

You have to buy a harness to add an OBD port (with CAN but no OBD), and that provides 12v power via the accessory circuit in the console (not permanent).

If you need permanent 12v you might need to research where to tap. The obvious one is the large 12v bolt under the rear seat.

Switched but safe.

This video shows how to safely get a switched 12 volt line for powering up to 10 amps of accessories in you model 3. It's located on the driver's side under the dash. This output has no other devices on it, and is electronically protected from overcurrent, so it's the safest place to tap 12v for auxiliary use.

I recommend a non-insulated 5mm spade connector, such as these from Amazon: https://amzn.to/2AAKq9P

I tested this for 10A continuous load, and it "trips" at 15A, so as long as your wiring can handle up to a 15A fault current, no fuse is needed. The car can sense a fault much faster than a fuse can blow!

Please see the update for clarification:
