Hi, does anybody know if the Model 3 does have a classic OBD interface, and if yes - where is it ?

As far I know the NA version has no ODB interface. The China one may, and we are unsure if the EU version does.
There is a company that makes an adapter, the OEM plug they use is located behind the panel under the rear USB ports. Last I checked it is expensive for a wiring harness and I am pretty sure it has something to do with monitoring if a child is in a car seat. So you don't forget that there is a child back there.
I've found some info on another forum but it still seems to be quite early to expect a 'plug and play' solution to get data out of the CAN bus, which is what I'm after. I suspect there's no easy way to get anything useful from the OBD port using that adapter.

I purchased the VeePeak Bluetooth OBD interface from Amazon.
Says it is compatible with various third party IDE / Applications on both iPad and Android.
Still another month (or more) until I get my Model 3 LR P-Lite, so I have no idea if it will work.
Hoping to show custom gauges (kw / hp, A, V, SOC details etc).

I joined the SmartCharge Rewards program by Fleetcarma - a sort of charging monitoring program to help the electric utilities optimize their system for EV use - and they sent me a small transponder device that connects via OBDII, and the adaptor thingie that connects to the connectors behind the seats. All for free. You disconnect the connector that's behind the panel between the seats underneath the rear USB ports, plug this adaptor between the 2 ends, and now you have an OBDII port.

Is the cable the same as the S/X one? Tesla Diagnostic Port Adapter Cable (Model X/S post Sep-2015) 680201861183 | eBay

Pictures - hmmm, I should have taken some when I was installing it. It's kind of a pain to get to, especially just to take some pics.
And no, not the same as that port cable - this thing has 3 ends - the OBDII, and the 2 ends that plug into the connector that you disconnect. So it's a pass through connector as far as the car is concerned, but the OBDII is attached to the appropriate wires.

EV don't require the On-Board Diagnostic connector (OBD now OBD2) as they don't have an Internal Combustion Engine.
In this YouTube video Jack Rickard explains in detail why and goes into detail about the subject matter.
He also sells a variety of options for connecting to the Model 3's CAN data (including one which replicates the OBDII connector - for $295)

You just spent an initial down payment on further tools required. What you bought isn't really compatible with TM3 directly. I have DashDyno SPD made by Auterra and I was hoping to use it to collect some data and display gauges and graphs. Turns out TM3 doesn't output legacy data through an OBD2 port. So I have a legacy tool collecting dust. You will probably need to buy something additional like @mccgregor listed above for a few hundred bucks, which in my opinion isn't a good financial investment for simple data tracking. No guarantee that your OBD2 reader will be compatible.
You can try doing it the cheaper route like how Wugz on Reddit does it via software, but you might not get to display custom gauges, and you'll probably have to do some custom coding to output custom gauges. Look at Wugz's additional posts for what data was able to collect.
