OBD Port? Model S Refresh

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.

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.
