OBD Port? Model S Refresh

[4SUPER9]

My last 3 MS's all had OBD ports in the top of the driver side footwell. This is missing in my wife's M3. Can anyone tell me if it is there in the refresh? I could really use it for 12V power access.

I don't nơ about the 2021 S and X but Model 3's OBDII is hidden behind the bottom cover under the rear vents.

Fantastic. Likely present somewhere on the S. Probably not enough of them out there, and not enough interest, to look for it yet.

I have an S but don’t know where to start looking

This question has been answered in other threads. The Model S refresh definitely has an OBD, as reported by multiple people and confrimed by myself

Driver side, left of the steering column, attached to the trim piece that holds the led footwell light bar and air bag.

Thanks, and oops. I was definitely not being helpful by not pointing out the location.

I connected blackvue to OBD port, it worked great until I locked up the car. Looks like car shuts down power to OBD, this is a different behavior than older MS.

That's perfect for radar detectors though if that's the case!

I ran the v1 savvy unit to the OBD on a 21 Plaid it didn't work so not sure why its different from my other ICE vehicles

What adapter should be purchased for the refreshed MS Plaid when using the OBDLinkMX+? Location of the connector? Pictures?

I bought following two adapters. I cut off other end of cig. lighter and re-wired with the other OBD adapter. Pin 4 is ground, 11 is constant, and 16 is switched. I use this to power my blackvue 24/7, works great.

Did the Savvy at least provide power?

It is in the section in between the seats deep down in the cubby in front of the cup holders. It was hard to find but it is there. WOrks well.

The V1 doesn't power on with the savy plugged into the one port

Are you using the switched ports off the OBD, or the unswitched? I found the unswitched (I can't remember, was that pin 5?) to be extremely unreliable. Also, my Escort 9500 would not power up off the OBD initially, and it gave me a "High Voltage" alert. My diodes fixed that. Running at 13.x now.

For others that may come to this thread, I've documented many different connection points for different Tesla vehicle variants, along with how they behave in different car modes and tested voltages and currents. For example, there are very few unswitched power sources with the new 2022 S/X. I include connector locations, pins, and pictures: Accessory Power Guide 12v/5v – TeslaTap

It also has several videos showing me connecting to many of the connection points if you're not sure where they are in your car (including ODB, the 12v power plug, and a number of internal connectors).

This is fantastic! Thank you!

Not sure if anyone answered about the M3 OBD port - Early Models 3s did not have one. All S/X/Y have them. As far as I can tell, they are not required on an EV but are handy for power and some accessory adapters that get power off of it. As for diagnostics, Tesla OBD ports do not have any useful data. You have to tap into other connectors and wire up an OBD connector to make some of the OBD scanners like OBDLink work as @MFrunkerOG showed above.
