M3 (Highland) OBD2 Adapter

I got my S3XY buttons + V2 Commander, and love them. Unfortunately, I am having issues with the Commander WiFi ScanMyTesla support not falling back to cellular for the internet on my phone, so I go completely off the grid when driving.

I have a spare OBDLink LX and would like to use it, so I ordered an adapter cable for the outgoing M3/MY (26 pin) which didn't fit and of course didnt tap in power.

Has anyone got any suggestions as to whether an alternate adapter exists? I think it will still need to splice in power like the Enhance Commander does.

I could build my own harness, splicing in an OBD2 connector to the S3XY harness or piggybacking off their connector, but not confident enough to take on that task if I don't have to.
