The Radio Info screen? Lower right and left buttons on the touch screen at the same time for 10sec then radio part info.

It’s coming out of the bottom of this bundle
Jimmy can you tell me the P/N for that fuse? It is a different size than the ones in the PDC and the parts guy couldnt figure it out

It’s a standard “mini” series fuse- 20 amp
Tada. Worked perfectly. Wasn’t sure what to expect when setting up, so drained the first tire for about 45sec, then horn honked 30sec later. Second tire drained 30sec, honk 30sec later. Next two tires honked at 15sec of draining.

That's the way we want to see it. Good job.Tada. Worked perfectly. Wasn’t sure what to expect when setting up, so drained the first tire for about 45sec, then horn honked 30sec later. Second tire drained 30sec, honk 30sec later. Next two tires honked at 15sec of draining.

I would doubt it. There is definitely a value called “TTPMS Present” in the BCM. It is set to No on the 2019s. I suspect that if that is not set to Yes you wont get the option. Worth a try though.

Jddirk is correct. You still have to enable the settings in the BCM. All that happened when I had him pull power to reset the radio is it sped up the process of the radio learning the new BCM settings. Otherwise, it might have taken a day or two of multiple drive cycles for them to show up.
I got it. Just had to pull the rear edge of the headliner away from the window frame edge. Just like @Phil T doc said to do. I used a wide hooked trim tool.
DO NOT remove that phillips screw. It screws into a clip that's pressed in. The clip popped out somehow and fell all the way down behind the trim panel. I had to pull the trim panels all the way down and fish it out with a magnetic wand. That lower panel isn't coming out easily with the seat installed. I'm not sure why they did it that way to begin with.

I posted pics of this early in the thread after @g00fy showed the TPMS enable option in AlphaOBD.
I left my radio overnight and it showed up the next day. I think someone else got it with just a few key cycles.
I got everything installed today but didn't have time to test the generic 433Mhz sensors. Too busy selling my other truck and getting this one buttoned back up before visiting some friends.
ETA: Just checked After midnight) and the pressure is now showing on the radio. I enabled it around 3PM and started/drove the truck 3 times.

So far, I have not had any success pairing my Tireminder 433Mhz sensors to the truck.
I have a feeling I may have an unofficial option installed I may never use.
I don't want to throw much more money at it, but if I can build something that lets me drop the 5 PSI the computer needs, I might still try.
If anyone can possibly confirm dropping to 0 PSI might trigger a sensor learn, please let us know. That's how the tireminder external sensors pair.
I did notice in AlphaOBD an option to pre-install or change the truck TPMS sensors by inputting an ID code, but couldn't find anything on the Trailer sensors.

Awesome. Still waiting on my sensors. Who spun them into the tires for you? What did they charge?

I had my rebalanced at the same time, $15 per tire at a local tire shop I try to support.
For those trying the tireminders, can you just barely crack them so they start leaking? That would keep some pressure reading in the sensor, wouldn’t it? I don’t know how they work though so just guessing. I have a second trailer and would love to find a cheaper option for it.

That's what I was doing. Let them leak for a bit.
I tried several things. Starting at target PSI, starting 10 pounds higher, etc. I timed some and then measured pressure and was usually @5-10 PSI change.
The two sensors I'm working with had been unpaired from the tireminder and it is off.
