It's this thread.
I finally went with the 5G Hub serial OBD board (similar to the SparkFun board, but smaller and includes the 16-pin connector).

Bought from DigiKey https://www.digikey.com/en/products/detail/5g-hub/OBDSTN2100R10/13530506
I have it permanently connected in the Jeep, feeding a RasPi Pico microcontroller and a touch LCD. It works nicely, just displaying 6 lines of OBD info. I'm working on a round-gauge library for it to pretty it up.
I also have one of these. I bought it because it’s compatible with the all of my vehicles and my moto, and the apps I use for them.
How is the connection on thus thing, Dawg? Does it connect fast when activated and stay connected reliably?
I like that it goes to sleep and will not drain the battery. I do not leave mine installed because when it is plugged in, the lights are always on.
I also have that VEEPEAK and it's a steaming pile. It was pre-claude the last time I worked on it, but our experiences were identical. Like pretty much unusable in any capacity.
I love my OBDLink, but it uses some sort of encrypted bluetooth or some such that prevented me from using it for my own hackery. That made me sad. I'm gonna look into your hardwired approach once I'm ready to re-tackle this project. We should probably collaborate or something.

@NashvilleTJ, With smartphone BT turned on, OBDLink MX+ typically connects on the first try with the app, although occaisionally requires a 2nd attempt. Once connected, I haven't experienced any drops whether during ignition on / engine off diagnostics for reading and clearing codes nor with engine running and viewing the app dashboard on my android phone or nav tablet
I just took some lousy pics showing sequence of OBD port device lights, i.e., 1st pic with no lights illuminated confirming truly in power-off "sleep mode", 2nd pic with the door open but no key on, showing the far LH green Power light solid and the far RH blue Link light flashing (ready to connect?) and lastly, 3rd pic shown with the app connected and ready for use. Its been plugged into the OBD port for several months with no adverse effects, as has my buddy's with his 2003 Rubi. Refer to post #3 for a clear image of device light terminology.
Yeah, I had heard that the OBDLink encrypted it's stuff, which stinks. That's another reason I gave up on bluetooth for these.
I have a VEEPEAK also and use the torque app to run it. I haven't had any issues connecting and staying connected. I mostly use it in the dashboard mode and use my phone to monitor a few things real time like coolant temp. adjusted gps speed ect... The torque app allows you to make custom dashboards with picture backgrounds and a wide variety for the number of gages with control limit alerts.
OK - You boys convinced me. Ordered this morning about 9:30, and it just showed up. I also downloaded the Torque App to my Android Tablet in the Rig.
Toby approves...
...although he doesn't look as excited as I am.
And just like that, it fires up, connects immediately, stays connected, and seems to work.
Set up a few gauges quickly. So far - I like it a lot.

Toby is giving doubting side eye vibes
Because he knows the answer to "Can I eat it?" is "No!"...
